Pop star and actress Lady Gaga might have had one drink too many at Pump, "Real Housewives of Beverly Hills" star Lisa Vanderpump's restaurant. Gaga took a nasty spill last night as she fell off the curb while attempting to get in her car outside of the West Hollywood spot, according to video footage obtained by TMZ.

The "American Horror Story: Hotel" star walked from Pump to the curb, escorted by Vanderpump, where her white convertible was waiting for her. Gaga wore a long red-and-black silk evening robe with a pair of black fuzzy stiletto slippers. Her blonde hair was pulled back in a tight bun and red sunglasses covering her eyes from the paparazzi.

The women walked arm-in-arm past reporters and Gaga remained silent, only making a hand gesture as if to say "oh, stop" when someone called out, "we love the robe!"

Vanderpump let go of Gaga's arm before she stepped off the curb to get into the car, and seconds later, Gaga was on the ground. Either she had one drink too many and couldn't balance in her heels, or her sunglasses prevented her from being able to see where she was going. Either way, Gaga recovered gracefully and flashed a smile for the cameras before she sat down in the passenger seat,"Entertainment Tonight" reported.
