Lindsay Lohan is looking great these days after spending 90 days in rehab. The 27-year-old star posted this selfie on Instagram yesterday showing off her long red and curled locks, and announced she’s back to work.

“#back@work! So grateful today! :)” she wrote.

The work Lindsay was happy about is shooting scenes for Eastbound & Down in Wilmington, N.C.

HBO confirmed Wednesday to E! News that Lohan will be guest-starring on the raunchy sitcom’s upcoming fourth and final season. The show is co-produced by Will Ferrell and stars Danny McBride as a former pro baseball pitcher who returns to his hometown to teach P.E. in a blaze of no-glory-at-all.
