Lindsay Lohan makes stage debut in Speed-the-Plow

Lindsay Lohan has made her stage debut in the West End, although her performance did not go entirely smoothly.

The Hollywood actress forgot her lines once during the second act of Speed-the-Plow and was helped by a prompt.

She plays the role of secretary Karen in David Mamet's Hollywood satire, a role that was originated by Madonna on Broadway in 1988.

One prominent critic described Lohan as being "out of her league".

But the Guardian's Michael Billington described Lohan's performance as "perfectly creditable", adding that she "holds the stage with ease".

"Whatever her colourful past, Lohan brings on stage a quality of breathless naivety that is far and away the most interesting thing in Lindsay Posner's otherwise tame, under-powered revival," he wrote in his two-star review of the play.
