Charlie Sheen at Odds with Selma Blair on "Anger Management"
In the FX series, the "Cruel Intentions" star plays his therapist, Dr. Kate Wales, but her future on the show is currently in jeopardy.
Reports say the 40-year-old actress complained to executives about his work ethic and in turn, the troubled 47-year-old actor threatened to not show up on set if the issue is not resolved.
The issue may be a huge problem for the network, which picked up four years' worth of episodes last year. "Anger Management" airs Thursdays at 9:30pm on FX.
