A$AP Mob hurled themselves into a packed crowd in Hollywood and allowed concertgoers to do the same … and a woman claims they left her in a world of hurt.

The group is being sued by a woman who attended their concert at the Fonda Theater in Hollywood back in 2013. Tammy Nguyen claims she was a VIP at the show when A$AP Mob took the stage at around 11PM. There was lots of crowd surfing during the evening, but it really intensified.

She says A$AP members, including Darold Ferguson, Jr. — better known as A$AP Ferg — were diving in the crowd, along with a bunch of fans. When Ferguson jumped, Nguyen says he nailed her.   And what’s worse, she says she had to fight her way through the crowd to get out, and security didn’t help.

She’s suing the group and Ferguson.
