Lady Gaga Unfazed By Bradley Cooper Cheating Rumors, Enjoys Girls' Night Out

Lady Gaga may have just called off her engagement with Christian Carino and is still plagued by romance rumors with Bradley Cooper, but the Oscar winner remains unbothered and seems to be embracing the single life.

Gaga recently enjoyed a girls' night out with Lisa Vanderpump on St. Patrick's Day. The "A Star Is Born" actress was spotted with the "Real Housewives of Beverly Hills" star at the latter's venue Pump and TomTom in Los Angeles, Entertainment Tonight reported.

Gaga and Vanderpump reportedly hung out in a corner nook close to the bar in Pump at around 11 in the evening. A source told the outlet that the two "did some guest DJing together."

A second onlooker told ET that Gaga and Vanderpump had a blast sipping drinks and dancing. According to Page Six, the two even "took turns playing music."

Joining them on their St. Patrick's Day celebration were Vanderpump's husband, Ken Todd and "Vanderpump Rules" castmates Billie Lee and Tom Sandoval. They were reportedly "all in good spirits and very friendly."

After a few hours in Pump, the group reportedly headed to Vanderpump's latest nightlife venue, TomTom Bar, where they chilled in the garden "into the wee hours of Monday morning."

Gaga apparently also interacted with some fans on St. Patrick's Day and gave them some words of inspiration. “I got to dance with Gaga and talk to her. … She was so sweet, and I told her how I’m pursuing acting, and she told me to never give up and [that] she believes in me. She could not have been sweeter,” an insider told Us Weekly.

Vanderpump also dished on her night out with Gaga on Twitter, where she said that she had "so much fun."

This was not the first time that Gaga had been spotted at Vanderpump's restaurant Pump. Back in 2015, the singer-actress was seen at the restaurant on two different occasions.

The "Shallow" singer has also collaborated with Vanderpump in the past. She invited the reality star and her "Real Housewives of Beverly Hills" co-stars olanda Foster, Kim Richards, Kyle Richards, and Carlton Gebbia to appear in the music video for her song "G.U.Y." back in 2014.
