Jared Leto Casts Doubt Over Jennifer Lawrence's Oscars Fall, Saying 'I Wonder If It's An Act'

She may be the new golden girl of Hollywood, but it seems not everyone has fallen for the charms of Jennifer Lawrence.

In fact, actor Jared Leto has claimed he is beginning to doubt how genuine the actress really is.

Jennifer made headlines when she was seen tripping over on the red carpet at the 2014 Academy Awards, having previously fallen over when collecting her award at the ceremony a year earlier.

However Jared - who scooped the Oscar for Best Supporting Actor for his role in 'Dallas Buyers Club' - has claimed he's not sure whether or not Jennifer is putting on her clumsiness for effect.

When asked about her fall, he told Access Hollywood: "You know, I'm starting to wonder if this is a bit of an act".

He also confessed that he and presenter Ellen Degeneres were having a laugh at Jennifer's expense when she presented him with his Oscar.

The 42-year-old explained: "What [Jennifer] didn't know was that Ellen [DeGeneres] was on the side…making, pantomiming [motions like], "Don't fall, don't fall!", and my mom and brother are all cracking up. I guess we don't have manners. You can take them out of Louisiana, but you can't take the Louisiana out of them, right?"

Both stars were pictured in Ellen's now infamous Oscars selfie, which became the most retweeted photo in Twitter history when it was posted.
