A little trip and fall won't stop Lady Gaga from saying hello to her Little Monsters. During her third Mayhem Ball show in Las Vegas on Saturday, the singer lost her balance and tripped while performing "Vanish Into You," right at the part of the show where she approaches the barricade to interact with her fans.

Aside from the singer's small slip, the Mayhem Ball tour has kicked off without a hitch. Gaga opened the trek July 16 in Vegas, playing a total of three shows at T-Mobile Arena. She'll next make stops in San Fransisco, Los Angeles, Seattle and New York City.

The complete setlist for Lady Gaga's 'Mayhem Ball,' as revealed in her tour's opening night at T-Mobile Arena in Las Vegas, developing live.
