While estranged wife Britney Spears worked on her dance moves back in Los Angeles, Kevin Federline celebrated his 29th birthday over the weekend in Las Vegas with his kids... and ex-girlfriend Shar Jackson.
Returning three weeks after a visit there with the kids while Spears was in rehab, FedEx arrived in town Friday afternoon with sons Sean Preston, 18 months, and Jayden James, six months.
After checking into Caesars Palace, Kevin Federline spent the remainder of the afternoon relaxing in the VIP cabana at Caesars' Venus Pool Club, a private, somewhat hidden topless pool adjacent to the public pool.
The birthday bash kicked off Saturday night, with the now-29-year-old K-Fed starting his evening at Social House, dining on Asian fare with 14 of his closest friends and family by his side.
But apparently that wasn't enough for him.
"He was talking on the phone and texting the whole time," said a source.
Later, Federline made his way to Caesars' Pure Nightclub, where his ex, Shar Jackson, was already present. Sadly, Jason Alexander was a no-show.
"As soon as his parents got to the club they immediately went to Shar's table on the other side of the club and hung out there for a while," a source says. "They were taking photos with her and catching up. It's pretty easy to see that they still care about her."
Meanwhile, a well-dressed Federline was clearly having a good time, hanging with his group and singing along to most of the music.
Drinking Jack Daniel's, Federline was rollin' VIP, hanging out in the VIP area most the night, waving to the crowd as they yelled for him.
At 2:30 a.m., Jackson returned to Federline's table to dance with his folks. Federline then grabbed the mic and said to the crowd:
"'My entire family came out for my birthday. My brothers are here, my mother, my father, my sister and even my ex, Shar Jackson, came out for this.'"
Eloquent, K-Fed. Eloquent.
