Rebel Wilson had to be rushed to hospital after suffering a concussion on the set of 'Isn't It Romantic?'

She recalled: "I was walking to meet Adam and Liam for a rehearsal when we were shooting an outdoor Hamptons scene, and I slipped down a grass hill.

"I got a concussion and was rushed to the hospital for three hours, and then came back and filmed a 16-hour day. I thought, how ironic, not from doing one of the crazy stunts, but from the grass having a bit of dew on it."

Speaking to People, Rebel added: "Two of my toenails came off because of the flats I was wearing."

Meanwhile, Rebel recently admitted it's a "challenge" dating in Los Angeles.

The actress thinks Hollywood's beauty standards are "very unrealistic" and joked that she finds it easier to date elsewhere in the world.

She said: "Los Angeles is a bit of a challenge. I remember when we shot 'Pitch Perfect 3' in Atlanta. Boy, was I popular there! I should move to a city like Atlanta. I was considered a 10 there. Not to say the people in Atlanta aren't good looking. But Hollywood's beauty standards are very unrealistic."

Rebel also revealed what she's specifically looking for in a boyfriend.

She shared: "I've been so lucky to create this awesome life for myself that I want to find that person to share it with.

"It can be a roller coaster being in the public eye, so I guess I [really just want] genuine niceness and supportiveness."
