VIDEO : Jennifer Lopez Accidentally Reunites With Casper Smart

Guess who?
On Monday, the singer and actress went out to the Cuban restaurant and nightclub El Floridita in Hollywood with BFF Leah Remini to celebrate a friend's birthday and bumped into none other than her on-again, off-again boyfriend Beau "Casper" Smart, who was also among the guests. He and J.Lo had most recently broken up last summer.
The three were seen popping in and out of the venue together and chatting outside. J.Lo seemed "happy," a source told E! News.
