These days, however, he's more than willing to lay his differences with his ex aside for the common good - even on his birthday!

Yesterday, for instance, Kevin turned 29 - but with Britney getting out of rehab and returning to her Summit Circle home, he found five hours to bring Sean and Jayden around to visit their reinvigorated mother. Kevin then returned to Tarzana with the kids only to find a deliveryman waiting with flowers and balloons. Hopefully they came from Britney as a token of thanks - Kevin certainly deserves them!
