X17 XCLUSIVE - Britney & Kevin Getting Back Together? OMG!!!

Well, spending time together is a start, anyway!

Saturday was a big day for the Spears/Federline fam! Daddy Kevin came to pick up his kids, Sean Preston and Jayden James, at Britney's Beverly Hills pad... and who was already at the house? His daughter (with Shar Jackson) Kori! Which means she must've spent the night, or at least the afternoon, at Brit's place!

PLUS, Kevin was inside the house for a good half an hour visiting with ex Britney and the kids...

AND there were NO bodyguards present - another first!

Do we see a reconciliation in this former couple's future?
