Looking Smart ... J.Lo looks on as Diddy and Casper shake hands
Diddy thrusts out his hand as he's introduced to ex-girlfriend Jennifer Lopez' new man Casper Smart at a Golden Globe Awards after-party.
It's never fun bumping into an ex - and when they're an A-lister, the encounter must be even more awkward.
But full marks to the rap superstar for behaving with grace towards the 43-year-old J.Lo's dancer beau - when the trio ran into each other last night [Jan. 14].

Their relationship ended in dramatic fashion, after shots were fired in a New York nightclub where he was partying with Lopez. The rapper was charged with four weapons-related offences, but later found not guilty.
The trauma of the trial spelled the end of the pair's romance - but there's clearly no hard feelings between the former flames.
They were even linked with a reunion after Lopez ended her most recent marriage, to Latin superstar Marc Anthony - and before she met toy boy Casper, 28.
