Fresh on the heels of breakup rumors, Adrienne Maloof stepped out with her younger beau Sean Stewart at Perez Hilton’s birthday party on Saturday night.

Although the pair arrived, arm-in-arm at the bash, which was held at the El Rey Theatre in Los Angeles, they didn’t seem to share the same interpretation of party’s pajama theme. While the 51-year-old divorcée showed up wearing a floral bustier, thigh-high stockings and a lacy black robe, Stewart, 32, on the other hand, donned sneakers, sweatpants and a layered T-shirt, and also sported a cut below his left eye.

Maloof was seen making the rounds at the party, stopping to pose for photos with Courtney Bingham, a decorating expert and fiancée of Nikki Sixx. “@PerezHilton BDay with the beautiful and talented @CBingham,” Maloof wrote in a tweeted photo on Saturday night.

But the bash wasn’t all play for Maloof, who busied herself with promoting her family’s new vodka line, Zing. The alcoholic beverage, which Maloof has also promoted on her Bravo reality TV show “The Real Housewives of Beverly Hills,” was one of the co-sponsors of the gossip blogger’s 35th birthday party.

The product was a source of tension between Maloof and her “Real Housewives” cast mate Brandi Glanville on a recent episode of the show. Glanville and Maloof have been feuding for months, since Glanville reportedly disclosed a secret about Maloof's family to other cast members. Although Maloof invited some of her cast mates to attend a launch party for the product, which was filmed for the show back in July, Glanville complained on-camera that there was nothing she wanted to do less than attend the party. She also complained to cast member Lisa Vanderpump that all of Maloof’s parties were held to promote various business products.

Maloof and Stewart’s attendance at the high-profile party comes just weeks after rumors that the two had broken up.

"It's over and she broke up with him," an unidentified source reportedly close to Stewart told E! Online. "She needs a man." 

“She and Sean definitely had an amazing spark, but it fizzled fast,” the source said. “They had a talk and, while they really care for each other, decided they would be better as friends. He was just a great guy who was making her laugh and forget about her past dramas.”

Shortly after the breakup allegations, Maloof and Stewart, the son of rocker Rod Stewart, were spotted together in public again at a boxing match.

Neither Maloof nor Stewart has commented on the breakup rumors.
