The 29-year-old singer stumbled on the curb after exiting Lisa Vanderpump's establishment. The Real Housewives of Beverly Hills star was helping Lady Gaga to her car when the pop star collapsed.
The "Applause" singer didn't seem any worse for the wear as she smiled and picked herself up. She vogued for photographers and exchanged air kisses with Vanderpump before her driver took her away in a white convertible.
In addition to Pump in West Hollywood, Vanderpump owns SUR Restaurant and Bar in the city and Villa Blanca in Beverly Hills. She and husband Ken Todd also own several establishments in London, including Bar Soho.
Lady Gaga last released Artpop in November 2013, and teased plans for her fifth studio album earlier this month. The singer will appear on FX series American Horror Story: Hotel as an "evil" hotel owner with a "nefarious" plan come Oct. 7.
