NEW YORK (AP) -- Lindsay Lohan was treated at a London hospital last week after she cut her leg in an accident at Bryan Adams' home, according to published reports.

The 19-year-old "Mean Girls" star had 10 stitches to close a gash on her shin after she slipped on a set of stairs Friday. Lohan was released from the hospital later that day, the reports said.

"She and her friends were preparing breakfast, with eggs and everything, and Lindsay was going up the stairs, carrying a ceramic teacup," her mother, Dina Lohan, was quoted as telling Star magazine.

"She had just come out of the shower so she was still wet and had some lotion on, and she completely flipped on the stairs since it was slippery. The teacup went flying, it was shattered, and one of the pieces cut Lindsay in her shin. It was an accident."

Lohan's publicist, Leslie Sloane Zelnick, told The Associated Press on Tuesday that Lohan was doing fine and was filming on schedule.

Adams, who photographed Lohan and other stars for his 2005 book, "American Women," wasn't in London when the accident occurred, Dina Lohan told Star.

Lohan is filming "Chapter 27," a film about John Lennon's killer, Mark David Chapman, also starring Jared Leto.

The actress-singer was treated at a Miami area hospital for an asthma attack in early January.
