Lindsay Lohan posted a photo on her Instagram account since leaving rehab writing that she was "back at work" and "grateful." According to Hollyscoop, the 27-year-old actress will star in her first acting gig since completing rehab on the HBO comedy "Eastbound and Down."

A source told E! News that Lohan is going to play the grownup daughter of Danny McBride, who plays Kenny Powers a former professional baseball player who has returned to his hometown to teach a gym class.

There haven't been many clues released about the acting gig except that the scene she is currently filming involves her playing a bride set in the future. "The Canyons" star looked healthy in the Instagram selfie as she sported long red curls and a light pink top.

The new job is following up on her hosting stint on late night show "Chelsea Lately." She also did an exclusive interview with Oprah Winfrey and filmed an eight-part documentary series as she tries to remain sober and get her life and career back together.

Winfrey released a clip of the interview recently which shows her grilling the actress about her past behavior.

"Do you think you can turn it around?" Winfrey asked Lohan. "What is it that you are addicted to?

At the end of the clip, the actress says: "I'm my own worst enemy and I know it."

While appearing on "CBS This Morning" the former talk show host said that Lohan was "honest" and "authentic" and "She looked good. She looked strong. She looked healthy."

"Eastbound and Down" premieres Sept. 29 on HBO and the Oprah Winfrey premiers on OWN Aug. 18.
