Before a romantic dinner at Red O, Mario Lopez and baby mama Courtney Mazza made an appearance at every C-lister's favorite milkshake shop in LA, but here's a nice twist: a portion of Lopez's milkshake sales will benefit the Boys & Girls Club of Venice.

It's all happening on Extra at The Grove! Not only did Mario "Dimples" Lopez swap fatherly advice with Ricky Martin, he also showed off his new baby Gia to the sexy singer. These two dads are two cute together!

Lopez also got up close and personal with the lovely Selena Gomez, who's looking more beautiful than ever, but really - how adorbs are Mario and Ricky?

New BFFs!

Mario Lopez is opening up on The Ellen DeGeneres Show about fatherhood and his upcoming VH1 reality show, Mario Lopez: Saved by the Baby.

Lopez, who admits to Ellen that he wants "three or four" kids, dished about how Gia's mom Courtney is doing ... and how she feels about adding more kids into the mix. The Extra host says:

"She's like one at a time. She's cool with that. She definitely wants them but I kind of want them right away and that's where we have our differences. I think it's cool when the brothers and sisters (are close in age.) I was raised close in age. When there is too much of a gap...I don't know, I just think it would be cooler."

Ellen even puts Mario on the spot ... asking him if he wants to propose right then and there. After he says, "No pressure. Thanks Ellen," his ladylove jokes, "Does that mean I have to say yes?"

We love a girl with a great sense of humor. Congrats, Mario!

Mario Lopez and girlfriend Courtney Mazza welcomed a baby girl, Gia Francesca Lopez yesterday in Burbank, California.

Mario and Courtney waited until the delivery date to learn the baby's sex, and Mario told Extra, "We are so overjoyed. What an amazing, wonderful and overwhelming experience to welcome our daughter into the world."

The couple met while costarring in Broadway's A Chorus Line, and this is the first child for both of them. Congrats!

No, Courtney Mazza did not give birth already! That's just Mario Lopez and fam at LAX last night. Of course, preggers Court does keep getting bigger every day! And that's good - Mario has previously said he wants a "real healthy fat baby" and claims he was a "fat, fat baby" himself...

Kinda hard to believe, but okay!

After all, the 28-year-old Broadway dancer is due in September! Mario Lopez took out his preggers girlfriend Courtney Mazza to Boa last night and the couple looked happy as can be.

Do they plan to get married? "That's on the way," Mario admitted at the Juno Baby Launch party over the weekend. An early congrats to the couple! By the way, how is it Mario stays so fit no matter what?

Wedding bells are in the near future for Mario Lopez and Courtney Mazza, who is pregnant with the couple's first child.

When it comes to walking down the aisle, the 36-year-old dimpled cutie tells UsMagazine.com, "That's on the way. We got a new house, a new dog, new baby... so it's on the way. There is no rush. It's exciting."

As for how his pregnant girlfriend Courtney, 28, is staying fit, she says, "I have a trainer and I work out with her and I walk my dog a lot. I watch what I eat but I don't deprive myself. The hardest thing to stay away from is bread and carbs.”

The girl has got will power ... and judging by her sexy preggo bod, it's working!

No word on the sex of the baby.

Okay, not really. Turns out they just bumped into each other the other night!

Buff-for-life Mario Lopez and his preggers girlfriend Courtney Mazza stepped out in Hollywood over the weekend and, by chance, ran into Wladimir Klitschko, the Ukrainian heavyweight boxer - who's also dating Hayden Panettiere!

The hot bodied buds shook hands and posed for some pix. Bromance alert!
