Someone still hasn't lost the baby weight!

Kevin Federline stopped to fill up his gas guzzling car in Calabasas, and the father of five looks like he's been eating one too many chicken McNuggets off his kid's plates! The former backup dancer hid his figure in baggy shorts and a red t-shirt.

His ex-wife Britney Spears, on the other hand, has never looked more fit! The pop star has been amping up the glam for her new gig as an X-Factor judge, and if anyone has any doubts she's perfect for the job, just ask Simon Cowell!

We wonder if K-Fed will bring Sean Preston and Jayden to sit in the audience?!

Britney Spears' ex-husband Kevin Federline chatted with TV Week about her engagement to Jason Trawick, and it sounds like he's genuinely thrilled about her announcement. "I'm really happy for her," he told the mag. "I think he's a great guy."

K-Fed added, "She's happy; she's doing really well. I want to say she's in a good place. I haven't spoken to her much since I've been [in Australia], both of us have been busy with her being on tour, but I do know from talking to the kids and talking to the kids' teachers that they're doing really good ... It's a good step in the right direction. I'm totally happy for her."

Kevin also spoke glowingly about Jason, saying, "He's a really good guy, I've heard a lot about him. I've spoken to him quite a few times as of now. He seems like a really good guy. The kids speak highly of him [and] her family loves him."

Though Kevin and Britney's two-year marriage ended in 2006, they have stayed on relatively good terms for the sake of their two sons, Sean Preston, 6, and Jayden James, 5.

Kevin also spoke about Britney's meltdown in 2007, telling the mag, "It was tough. [They were] just very, very, very dramatic times. I had to do what I had to do for the safety of our children. But at the same time, it tears my heart to pieces to watch your ex go through that, let alone watch anybody go through that. It's horrible. It was a completely dramatic, depressing stage of my life that I'm so glad I'm over and get to leave behind. It was tough."

Kevin Federline is a dad ... once again! Britney Spears' ex hubby's girlfriend Victoria Prince has given birth to Jordan Kay, according to Us.

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!
