Britney & Kevin On Amicable Terms

As the weather begins to heat up, Britney Spears’ relationship with Kevin Federline has become distinctly less frosty, and in recent weeks, K-Fed, 30, has even warmed to his ex.

“Kevin drove up to drop off the kids on May 29. Usually, he has the bodyguards do that, but clearly Britney and Kevin’s relationship has improved to the point where he has no problem handing them off to her himself,” a family friend tells OK!. “It’s all about the boys these days.”

In that spirit, Britney has even been spending quality time with her sons, Sean Preston, 2, and Jayden James, 21 months, hosting a pool party and barbecue in the backyard of her Studio City, Calif., home on May 31.

And while Britney, 26, is still working hard to get better, Los Angeles Superior Court Commissioner Reva Goetz agreed with Brit’s lawyer on May 29 that the star cannot capably participate in her own legal proceedings.

Instead, Britney has been squarely focusing her energies on being the best mom she can be to her boys — and her newly civil relationship with Kevin doesn’t hurt. “Successful co-parenting has to start with at least a camaraderie between parents,” Kevin’s lawyer, Mark Vincent Kaplan, tells OK!.
