We guess he's not the type to sit on his couch with Ben & Jerrys and cry!

Jason Trawick stepped out for dinner at Aventine restaurant in Hollywood last night, and Britney Spears' former fiance was all smiles as he met up with pals for a meal. The newly single agent seems to have undergone a post-breakup makeover, as he was sporting a new mohawk haircut and looked uncharacteristically stylish in motorcycle boots, jeans, and a leather jacket.

The 41-year-old must have enjoyed his guys night out, because he didn't leave and head home until 3 a.m.!

He might not be engaged to Brit Brit anymore, but if you believe the rumors he's still enjoying sexy time with the pop princess! "She [Spears] and Jason have slept together since the split," a source told Life & Style.

So why did they call it quits to begin with?

"Before, they were always fighting about getting married and having kids. They're getting along much better since not being engaged," the source adds.

Something is making Mr. Trawick grin...

Britney's ex, Kevin Federline, and her fiance, Jason Trawick, were apparently trained to do grocery shopping ... we've gotta hand it to Brit for getting these guys to participate in domestic duties!

Meanwhile, KFed's got other dooties to deal with. He's got a year-old baby with girlfriend Victoria Prince.

Perhaps the question is ... which couple will beat the other to the wedding chapel? Jason and Britney are engaged, but recent reports claim their engagement is on the rocks and Brit may be having second thoughts.

Spears is busy taping American Idol and after not working for so many years, perhaps the stress of her hectic show schedule is getting to her?

As for Federline, he hasn't even popped the question to Prince. Better get a move on, KFed!

Are wedding bells finally ringing for Britney Spears and Jason Trawick?

Britney's BF spent Monday afternoon at the Mouawad high-end jewelry showroom in Los Angeles. A source tells X17online that Jason, 39, was spotted chatting with jeweler Pascal Mouaward around 1 p.m. They spent an hour talking about engagement rings for Britney, 29.

"They discussed diamonds from the Mouawad private collection. It's Jason's first visit with Pascal," the source tells X17online exclusively.

It looks like Brit is headed to the altar again -- congrats, Queen B!!!

Jason Trawick has the need for speed! Of course, we're talking about the red motorcycle that Britney Spears' beau was cruising on in Redondo Beach. Perhaps a gift from Brit?

Riding without a helmet is certainly not the best example for Brit's younger boys Sean and Jayden. Hopefully the boys realize that safety should come first.

We have a feeling Brit will forgive her man for ditching the protection while on his bike ... considering how strong their relationship appears to be. While at the MTV VMA's, Brit said the following after accepting an award:

"First I'd like to thank God, for blessing me so much. And my beautiful family -- my two boys, Jayden and Preston, Mommy loves you so much... My management team... And to all my fans! And Jason. I love you!"

Vroom, vroom!

Britney Spears could be an engaged woman! This morning on KIIS-FM, Ryan Seacrest's co-host Ellen K said that Brit would be announcing big news today about her and beau Jason Trawick on Twitter.

So we thought hmmm ... engagement? And then we realized Brit was sporting some new bling Wednesday when she headed to dance rehearsals for her tour. Could it be???

If Brit does make an engagement announcement ... talk about great timing considering the mama of two is gearing up to begin her Femme Fatale tour. This will certainly generate publicity!

Over the years, Brit and Jason's relationship has been rocky both professionally and personally.

In May of 2010, Jason stopped acting as Brit's agent in order to "focus on their personal relationship." Looks like they're plan may have worked!

Let's hope they'll stay together till' the world ends.

After watching the game from inside her Mercedes G-Wagon last week, Britney Spears emerged to see Sean Preston batter up at the baseball diamond Sunday.

Jason Trawick escorted his lovely lady -- who was wearing a bright spring floral print with wedge heels -- and even bought a Coke for her to sip in the sunny Valley heat.

Meanwhile, daddy Kevin Federline gave Sean some batting tips ...

It appears the couple's love of soda has rubbed off on Sean! Jayden, however, found another way to cool off ...

Adorable!

Jason Trawick was looking mighty suspicious while hanging on the streets of Beverly Hills with his hand behind his back. Can you guess what Britney Spears' beau was trying to hide?

Find out ... after the jump.

What on earth was Jason Trawick doing in the back of a cab outside of Trousdale late last night? Sure, it could have been a funny angle, but we have to wonder why he's bent over like this with his underwear peeking out...

Anyway, Lance Bass and the Situation also showed up to Brent Bolthouse's West Hollywood hotspot on Tuesday evening, and click after the jump to see who else was there! Hint: we'll see him in a pair of tights on the big screen this summer...
