If there is one person you need to see before heading to rehab, it's Charlie Sheen.
Lohan will play herself as a patient who develops feelings for Sheen's therapist character. Her episode is schedule to start shooting next week, and the episode is slated to air in April.
This will not be Lohan and Sheen's first collaboration. The duo also cameo'd (and ended up in bed together) in Scary Movie 5.
On Monday, Lohan pleaded no contest to giving false information to a peace officer and to reckless driving, and admitted to violating her probation. The deal calls for Lohan to serve 90 days in a locked rehab facility, 30 days of community labor, 18 months of psychotherapy, fines and restitution to victim.
