OK! Exclusive: Brit & K-Fed's Secret Meeting

Despite their differences over the last year, Britney Spears and her ex-hubby Kevin Federline have one thing in common — they'd both like to avoid going to trial this summer over the custody of their two young sons Sean Preston and Jayden James.

On Thursday, the pop singer, her father Jamie Spears and K-Fed managed to sneak away to a secret location where they and their attorneys began to try and hammer out an out-of-court custody deal ordered by commissioner Scott Gordon.

However, the all-day meeting (rumored to have been at a 5-star hotel) ultimately resulted in nothing. Both Brit and K-Fed refused to give an inch beyond the current custody status: K-Fed has temporary physical custody and Britney has visitation, which now inlcudes one overnight visit per week.

The long, drawn-out conference seemed to take its toll on the recovering pop star. An eyewitness tells OK! that following the meeting, Brit went directly back to her Studio City home at The Summit and then headed to the Ritz Carlton Hotel where she promptly booked a massage and sauna session.

Looks like the August trial date is still on — for now!
