Lohan, 28, has been performing in David Mamet's play Speed the Plow on London's legendary West End, but now her role as Karen has come to an end.
The Mean Girls star tweeted out messages of gratitude today to David Mamet, the playwright, Lindsay Posner, the theater director, fellow actors Nigel Lindsay and Richard Schiff and the entire staff and crew.

Lohan credits Oprah for being "a part of this process and happiness" and has even called her a "fairy godmother." Oprah aired Lindsay, a docu-series on her OWN network and showed the actress on her road to recovery after a period of public crisis.
When Lohan spoke to the Telegraph in October about the play, she said, "I like the idea of being able to fight for what I lost, essentially." She said, "I lost a lot of… I wouldn't say… I don't think 'respect' is the word… trust from a lot of people. And I don't mind gaining that back."
With one play over, it remains to be seen if Lohan will do another theatrical work -- though she did reference Oleanna, another Mamet work, in one of her tweets. The play was last revived on Broadway in 2009, when it starred starred Julia Stiles.
Speed the Plow is a satirical play about the American movie business, and Lohan's character Karen is a secretary who turns out to be much smarter than she appears. When the play premiered on Broadway in 1988, Karen was played by Madonna.
