Lindsay Lohan said she vows not to miss any shows or rehearsals for her upcoming play in London's West End, Speed-The-Plow.
The actress, who has gained a reputation for not being reliable in such matters, said "that's not going to happen" this time.
"I'm at a place in my life where I like the commitment. I'm looking forward to that part of it," she told the BBC.
"I want to be known for my talents and my work that I create, rather than a tabloid sensation," she added. "However long it does take, I'm willing to do it. I'm willing to work for it."
