After finishing rehab just two weeks ago, Lindsay Lohan is already back to work.
A rep for HBO confirms to ABC News that the "Mean Girls" star will appear in an upcoming episode of "Eastbound and Down."
In fact, Lohan, 27, has already taped an episode. The upcoming season for the R-rated comedy is the fourth and final for the show, starring Danny McBride and set to return Sept. 29.
Just two days ago, Lohan posted a picture of herself on Instagram with the caption, "#back@work! So grateful today! :)"
Back to work is right! In addition to the HBO show, she guest-hosted "Chelsea Lately" earlier in the month and her interview with Oprah Winfrey will air Aug. 18 on OWN.
Lohan checked out of her court-ordered rehab late last month after spending 90 days in treatment.
