Maybe Julianne was just trying to show off her moves from Burlesque and Rock of Ages — or maybe it was revenge against Gavin's former partner, Karina Smirnoff, who was also at the club. Karina is set to dance Season 15 All-Stars with Julianne's original Season 4 winner, Apolo Ohno, and Julianne is kinda sad to lose her man. (Speaking of her men, where was Ryan Seacrest?)
According to People, Julianne and Karina were joined by DWTS pros Derek Hough and Chelsie Hightower at Gavin's concert Sunday at the Greek Theatre in L.A. Afterward they went to the Living Room Lounge at the W Hollywood for the Sunday Jazz Series.
People says Twilight stars Kellan Lutz, Ashley Greene and PLL's Lucy Hale were also there. Weirdly enough, Michael Bolton was also on hand, although his DWTS Season 11 partner, Chelsie, said he wasn't up for a dance.
One onlooker seemed surprised by Julianne’s lap dance for Gavin since, "It was in front of her brother and their whole DWTS crowd!" Meh. Derek’s seen it before, especially in his own Rock of Ages cameo. This is a very close family!
