Hollywood got extra glam for the opening of Nine Zero One salon’s new location on Melrose Place in West Hollywood on Saturday night.
Riawna Capri’s longtime celeb clientele came out to support the hair guru and to have a beauty-themed night.
After, Hough sat down to pose for a caricature while Dobrev was a social butterfly.
“She was in good spirits and was letting loose,” says a source about the star, whose ex Ian Somerhalder recently got engaged to Nikki Reed.
“She always seemed to be talking to someone new and at one point in the evening briefly took her heels off and carried them, walking around the salon barefoot!” the source tells PEOPLE.
But the night wasn’t all about the ladies. Breaking Bad star Aaron Paul and his wife Lauren were the first celebrities to arrive at the salon just after 7 p.m.
“He was really attentive with her. They spent about 15 minutes sitting down having a conversation together as if they were on a first date,” an onlooker says. “When a friend came up and joined their conversation, he held her hand.”
The Pauls also weren’t the only couple who made the event a date night: newlywed Ashley Tisdale brought hubby Christopher French.
“She looked really cute and bridal in a strapless white lace jumpsuit,” the source says. “They barely left each other’s side, and French looked on proudly when she posed for a caricature.”
Tisdale did break away from her hubby around 9:30 p.m. to jump in the photo booth and pose for a group photo with Dobrev, Hough, Once Upon A Time‘s Jennifer Morrison and Zelda Williams.
Williams made a fashionably late entrance around 9 p.m. and spent the majority of the party standing in the hallway talking to Dobrev.
“The two were very friendly and chatty, but Zelda was much more mellow and in less of a party mood than the rest of the crowd,” the source says
Other celeb attendees at the event, sponsored by Black Velvet Toasted Caramel Whisky, included Kellan Lutz and Olivia Holt.
