Sienna Miller cut her own hair

Sienna Miller chopped off her own hair.

The 'American Sniper' star claims her new shorter hairstyle was initially a "disaster" because she cut it herself in a bid to look different in one of her upcoming movies.

She said: "I lopped it off and it was a disaster. Bradley Cooper and I did another movie [the Untitled John Wells Project] after this one ['American Sniper'] where I played a chef and I decided that I had to look really different so I gave myself the worst haircut you've ever seen.

"I kind of half did it and then my friend took over but it was kind of a half short fringe, bangs and an undercut which is still growing out, the whole underneath is still shaved, so it was a disaster that has suddenly grown into something manageable!"

Meanwhile, the blonde beauty admits she is very nervous about starring on Broadway.

The 33-year-old star is set to take over the lead role of Sally Bowles in 'Cabaret' from Emma Stone in the production at Studio 54 in New York City next month, but admits she usually only sings when she's drunk.

The British actress told 'Live with Kelly and Michael!': "I've never sung or danced in public unless inebriated in karaoke."

She also told the 'Today' show: "I'm terrified, of course I am. By the way, if I wasn't, I'd be really worried because it's singing and dancing on Broadway. This is a big deal."
