Bennifer is long gone -- but never forgotten. With current boyfriend Casper Smart beside her, Jennifer Lopez joined the room at the Beverly Hilton on Sunday Jan. 14 in giving Ben Affleck** -- her ex-fiance -- a standing ovation for his Best Director and Best Picture Golden Globes wins for Argo. (A source told Us Weekly that Lopez, 43, was "beaming" and "paid close attention to the stage" during her former love's triumph.)

Indeed, the singer and Parker actress happily encountered two other exes -- Diddy and Bradley Cooper -- at the Globes and their afterparties. And that's no biggie, Lopez told Ellen DeGeneres** during a Wednesday Jan. 16 appearance on ELLEN. "[It's not awkward], because I see them a lot," she said. "Because we're in the same business. We run in the same circles."

"So it was a nice moment," she gushes of Affleck, who now has three kids with Jennifer Garner, his wife of seven years. "It was a nice to see him have that moment. I was really happy for him." (Lopez's post-Affleck marriage to Marc Anthony ended in July 2011.)

These days, Lopez is all about dancer-choreographer Smart, 25, who tagged along for her recently wrapped world tour. "It was actually great because I was away from home for so long so to have that support was actually a nice thing. It was a nice thing."

She added: "The babies [twins Emme and Max, 5] were there. My mom was there, my cousin was there. I just took the whole family and just left for months. But it was nice!"
