David Arquette's publicist says the actor has entered rehab.
In an e-mail Monday to The Associated Press, Cindy Guagenti says she has "no further information at this time."
Arquette and Courteney Cox announced their separation in October after 11 years of marriage. They have a 6-year-old daughter, Coco.
The 39-year-old actor has appeared in the "Scream" movies and co-starred alongside Drew Barrymore in the 1999 romantic comedy "Never Been Kissed."
The couple met on the set of the film "Scream" in 1996 and married three years later.
While the pair are inserting some space into their personal lives, their careers remain intertwined.
They are co-starring in the fourth installment of the "Scream" series, which is due out this year.
