"We have resumed normally this week," a show rep says. "The show was on hiatus last week and the entire cast is back on set today."
On Monday, Sheen, 45, and Mueller, 33, filed separate divorce petitions in Los Angeles. The actor is seeking joint physical and legal custody of their 1 ½-year-old twin boys, while Mueller is asking for primary physical custody with visitation for Sheen.
The actor's divorce filing comes days after an Oct. 26 hospitalization in New York, following an incident in the Plaza Hotel where Sheen was found drunk and reportedly naked after allegedly trashing the room.
Sheen also reported to the set of a friend's movie, She Wants Me, where he filmed a cameo on Oct. 28.
