Selena Gomez falls during performance just days after Justin Bieber's stage stumble

Not even a week after Justin Bieber fell off the stage during a concert in Canada, his ex-girlfriend, Selena Gomez, takes a tumble.

During the Tulsa, Oklahoma, leg of her Revival World Tour, the 23-year-old singer slipped and fell while performing "Kill Em With Kindness." Gomez recovered nicely and was quick to make light of her blunder. "First fall on the whole damn tour, can you believe it in Tulsa?!" she said, laughing. "Well, I'll be damned."

Gomez's godson, Aiden, was at the show to witness her falling, and looked beyond adorable with his little headphones on during the concert. "My godson watching his tia on stage," she captioned the cute pic. "@jaycosme -- Happy Father's Day."
