Sienna Miller ‘sporting stitches and black eye’

Sienna Miller reportedly had to get stitches for an injury she sustained on the set of Cabaret.

The American Sniper actress is currently portraying character Sally Bowles in the Broadway musical production, taking over the role from Emma Stone last month.

And according to the New York Daily News, Sienna has already been injured after walking into a prop when the stage went dark during a weekend performance.

The outlet reports she made an appearance at Upper East Side eatery Serendipity 3 on Monday afternoon with a huge gash on her face.

“[Sienna] entered the restaurant wearing a big pair of sunglasses, but when she took them off to greet the host, she was sporting a black eye and stitches,” a source told the newspaper. “She took off her sunglasses and said, ‘Oh no, don’t look at me, don’t look at me.’ ”

However, Sienna’s physical affliction doesn’t seem to be affecting her work in the slightest.

The injury is said to have happened Saturday night and she was right back at it on Sunday performing a matinee showing of Cabaret. Sienna’s black eye was noticeable when she made an appearance in a video her co-star Alan Cumming posted on his Instagram account on March 8.

Onlookers claim Sienna, 33, seemed to enjoy her time dining at Serendipity 3 with fiancé Tom Sturridge and their two-year-old daughter Marlowe during her well-deserved day off from performing in Cabaret.

The actress has previously spoken about how she is putting her own spin on the portrayal of classic character Sally Bowles.

“This part, it sort of has to be your own version,” she explained to Vanity Fair. “It’s really bottomless, and it’s really open for interpretation, and there really are a million different ways that you can go with it.”

Sienna will appear until March 29 at the Studio 54 theatre.
