They may be in the early stages of finalizing their divorce, but Heidi Klum and Seal are still fully committed to their four kids!

The former couple reunited Leni's 8th birthday party at a lavish mansion in the Hollywood Hills, on Saturday afternoon, and she definitely got the A-list treatment -- the party had professional caterers!

Despite the fact that the little girl isn't his biological daughter, the musician began dating Klum when she was preg, and formally adopted Leni as his own after her birth. Little Leni, who's full name is Helene Boshoven "Leni" Klum Samuel, doesn't have any contact with her real father, director of the Italian Renault Formula One team, Flavio Briatore.

The German-born model filed for divorce on April 6, and the ex-pair have been hammering out a custody agreement which allows the 49-year-old singer joint legal custody of the Leni, 7, Henry, 6, Johan, 5 and two-year-old Lou, while Klum will have primary physical custody of the kids.

Despite the spilt, they're still keeping the peace!

As Heidi Klum and Seal prepare their divorce and as Seal is off promoting his new album, Heidi's home with the kids, going it alone ...

The soon-to-be single mom took her brood to their weekend activities Saturday -- Henry and Johan to karate, and Leni to ballet. And what we noticed were the kids' superstar styles -- Henry's sporting an edgy Mohawk and Leni, 6 1/2, is carrying a cell phone!

The Project Runway boss was no less chic -- she wore a $3200 Rick Owens leather biker jacket to run errands. Hey, in LA, weekend casual is still haute couture!

While promoting his latest album Soul 2, Seal took a moment to discuss with Access Hollywood's Billy Bush about how he told his four kids about his split with wife Heidi Klum after seven years of marriage.

Seal tells Bush:

"Just explaining to them that things will be different, you know, without going into too much detail. The main thing is to make sure that they feel that they're loved, make sure that they understand that their parents love each other, make sure that they understand if there are any changes, it is absolutely nothing to do with them."

Seal, 48, and Heidi, 38, are parents to Leni, 7, Henry, 6, Johan, 5, and Lou, 2.

Despite the fact that he is currently going though a divorce with Heidi Klum, Seal never stopped smiling as he made his was though LAX, and a huge pack of photogs on Thursday evening.

The newly single singer is currently on a promotional tour for his latest album, which is kind of unfortunate, considering he'll have to face constant questioning about the recent split.

But the father of four is still adamant about keeping his wedding ring on, for now. Seal told Ellen during an interview this week, "I think it’s just pretty much a token of how I feel about this woman. We have eight years. Eight wonderful years together.
Just because we have decided to separate doesn’t necessarily mean you take off your ring and you’re no longer connected to that person. We will be connected in many ways ‘til the rest of our lives."

Seal stopped by the Grove today to promote his new album, Soul 2, and the singer pasted a smile on his face and waved to fans during a break from his interview.

Seal is still wearing his wedding ring, and he told Ellen DeGeneres the other day that he has no plans to take it off anytime soon. “Just because we have decided to separate doesn’t necessarily mean you take off your ring and you are no longer connected to that person," he said. "Will we wear the ring for the rest of our lives, who knows?”

Seal continued, “[Heidi is] still, in my opinion, the most wonderful woman in the world…We still very much love each other. To say neither of us were grieving would be an out and out lie.” While his marriage may be up in the air, the Grammy winner certainly isn't letting his personal life affect his promotional tour!

Seal isn't shy about speaking out about his split with wife Heidi Klum ... or discussing the possibility of a reconciliation.

The 48-year-old "Kiss From A Rose" singer appeared on CNN's Piers Morgan Tonight and said the following:

"It may happen, I can't speak for her. Is it irreparable? You can never say never. The thing I love most about us is that we are a team … that won't change, whether we get back together or not."

Seal and Klum were married for almost seven years. He adds:

"I don't know at this point, to be honest [if I want to reconcile]. If it were that easy – if there weren't problems, we'd still be together. That is the reality ... I'm still wearing my wedding ring because I'm still married to this incredible woman."

The singer is currently promoting his latest album Soul 2.

Stepping out publicly for the first time since confirming his split with wife of seven years, Heidi Klum, Seal stopped by The Ellen DeGeneres Show to promote the release of his new album, and open up on his recent split.

The "Kiss from a Rose" singer, who was still wearing his wedding ring, tells Ellen of the recent breakup:

"I think we were shocked. You go into these things with the greatest intentions when you say 'I do' and you say '’til death do us part.' Those vows hold value. They are not just words.

These things happen. We pretty much said how we feel and made it clear in the release statement. But, for intensive purposes of this show, you just grow apart after awhile.

You try and you work through it and the thing that you quickly realize when you are married and you become a parent you do the best that you can. It makes you actually appreciate your parents a lot more."

Seal went on to praise the Victoria's Secret Angel, confessing:

"The thing that I’m most proud about this great woman who married (and I really do mean that from the bottom of my heart), is that together she has given me four incredible gifts…four beautiful children.

She still, in my opinion, the most wonderful woman in the world. I think our priority was to remain civil and do this thing with dignity. We still very much love each other.

It’s not a question of we were never to follow suit of some break-up or separations that you hear about, especially in our industry. It’s a shame. To say that neither of us were grieving would be an out and out lie (and I don’t mind telling you that).

I think the operative here is that we are civil to each other and we both have a tremendous amount of respect and love and we try and do this with as much dignity as we possibly can. And of course, when you have four children, you hope and pray that the rest of the world will respect that we have four children and that their little hearts are at stake too."

The Grammy winner later discussed the reason why he decided to keep his wedding ring on, revealing:

"I think it’s just pretty much a token of how I feel about this woman. We have eight years. Eight wonderful years together.

Just because we have decided to separate doesn’t necessarily mean you take off your ring and you’re no longer connected to that person. We will be connected in many ways ‘til the rest of our lives…. though our children and also through this tremendous admiration, respect and love that we have for each other.

Will we wear the ring for the rest of our lives? Who knows? But right now it feels really comfortable on my hand so I have intentions of taking it off anytime soon."

The German supermodel reportedly filed for divorce from Seal due to his "hard partying ways" and "volcanic temper."

Are you shocked over the Heidi/Seal split?

Seal is about to embark on a big publicity push for his upcoming album Soul 2, and X17online has learned that his label, Warner Bros. Records, is not preventing media outlets from asking questions about his recent split from Heidi Klum.

The "Kiss From A Rose" singer is taping The Ellen DeGeneres Show Monday afternoon. As for whether Ellen will ask questions about his separation from Heidi, a publicist at Warner Bros. Records tells X17online exclusively:

"Out of respect to Seal, we don't think Ellen will go there with the questioning. She's not tabloidy. If this were Wendy Williams, that would be different."

The couple's split being announced the day before Seal's big record release is "purely coincidental," the rep at the label tells us. She adds:

"Seal and Heidi's split has nothing to do with his new album coming out tomorrow. He's had these promotional dates scheduled for months. This is horrible timing."

But as we know, even bad publicity can work in someone's favor. The publicist admits:

"As sad as it is, their split has definitely generated awareness to the new album. We'll support him as best we can."

The first single “Let’s Stay Together" from the new album was released on November 1. Pretty ironic title, don't you think?
