It's comforting to know that even a major celebrity can do something incredibly embarassing when meeting a fellow celebrity.
For Sophie, it had everything to do with her tongue movements when she met the Biebs.
While on The Late Late Show with James Corden, Sophie shared the moment she embarassed herself meeting Justin in a random house in Miami.
She was with Joe Jonas at the party when someone asked her if she wanted to have a tour of the house. She said yes and ended up in a room where JB was topless and getting a head massage.
She introduced herself and then ran into a closet and cried, before finding Joe and going back to meet Justin again. "Then I came out with Joe and Justin goes, 'Yo, Joe, I heard you've got a new girl.' And Joe was like, 'Yeah, there she is. She's over there.'"
Then, this is where she explains how her tongue had a mind of its own, sticking out and doing some sort of licking manoeuvre. "I don't know what came over me," she said. "Joe has never let me live it down since."
So basically, she was this GIF to Justin:
"I'm sure he's used to it," she continued. "It can't be the strangest thing anyone's done to him!"
