She has also strayed from the movie industry. Her last film, the 2007 horror flick "I Know Who Killed Me," earned her two Razzie Awards for worst actress. She does, however, retain ad campaigns with brands including Fornarina jeans and Sevin Nyne spray tan, which she promoted on DeGeneres' show.
It doesn't look like she'll rebound with her upcoming film "Labor Pains," in which she plays a woman who fakes a pregnancy to save herself from unemployment.
Instead of hitting the big screen, "Labor Pains" will premiere on ABC Family in July and come out on DVD a month later.
Lohan, who recently told E! News that she wants to have her "own charity, do work overseas [and] be in Oscar-nominated films," once boasted one of the most promising careers in modern-day Hollywood. She charmed as a child star in Disney's 1998 remake of "The Parent Trap" and won critical acclaim in 2004's "Mean Girls."
On "The Ellen DeGeneres Show," Lohan said being single has given her time to focus on staging a comeback. She thanked family and friends, including actress Natalie Portman, for their support.
"I feel like I want to get my career back in shape," she said. "There are some shows I'm producing that I'm really excited about. I'm doing a movie in October. ... You know when people are together so much it gets really difficult and you forget who you are because you're more concerned about being with the other person. I think [the breakup has] been really good for me. ... I've had great people surrounding me and I've just been working every single day."
