FLIRTY FLOCKHART BONDS WITH BON JOVI

ALLY McDREAMER:

In the john at LA's swanky Ago, Calista Flockhart -- who'd been chatting nonstop with very happily married rocker Jon Bon Jovi at the VH1 Awards after-party -- seemed to be making a mountain out of a molehill when she said very loudly to Ellen DeGeneres, "I'm SO drunk, I can't believe it! I have a 6 a.m. call tomorrow -- but Jon Bon Jovi won't let me LEAVE!" Whatever Calista's fantasy was, it ended when she left the loo -- and found Bon Jovi deep in conversation with a chic brunette!
