Lisa Vanderpump and Lady Gaga showed off their friendship at Vanderpump’s Los Angeles restaurant Pump on Wednesday night.

We can’t be the only ones who had no idea that these two had even met, let alone counted each other as a BFF. But Gaga and Vanderpump are reportedly longtime friends who spent a night catching up and indulging in some adult beverages all the while.

It’s just a good reminder that, aside from starring in reality shows like The Real Housewives of Beverly Hills and Vanderpump Rules, Vanderpump is also a successful entrepreneur in the entertainment industry with her restaurant, books and philanthropy.

Vanderpump even admitted that the girls were #misbehaving in her Instagram selfie with the pop singer.

Their friendship isn’t the only thing that was flaunted last night, either. Gaga also displayed her seamless ability to recover from a tumble after tripping on her way out to the car.

As we can see from the TMZ video, Gaga was hardly fazed by the fall. Though she gripped her white convertible for support and relied on the help of a gentlemanly security guard to get her back on her feet, she was all smiles. She even exchanged a few friendly goodbye kisses with Vanderpump before getting into her white convertible and heading out.
