That's the buzz after Nick and Gigi were photographed together, presumably out on a double date with Joe Jonas and his girlfriend, Blanda Eggenschwiler.
Joe, Nick, Blanda and Gigi were spotted out at the movies on December 2.
Of course, pics of Nick and Gigi in close proximity don't exactly prove they're dating, but the couple were also seen together during a recent trip to Disneyland.
Check out the pics of Nick and Gigi at the movies and at Disneyland.
Gigi (real name Jelena) is a model who got her start with Baby Guess--her mom is Yolanda Foster, who stars on Real Housewives of Beverly Hills.
