Cox backs ex Arquette as he goes to rehab

Actor David Arquette, the estranged husband of former Friends star Courteney Cox, has checked into rehab to deal with alcohol and depression issues.

Arquette (39) and Cox (46) announced in October that they were undergoing a trial separation after 11 years and one daughter together, but still loved each other "deeply".

Since then, both have been linked to other people, while Arquette has been unusually open about his marital woes and his subsequent sexual and drinking activities.

People magazine said Cox was supportive of her husband's decision to get help. "I really admire David and his choice to take charge and better his life," it quoted Cox as saying: "I love and support him."

The couple met on the set of the 1996 horror film Scream and married three years later.

But while Cox enjoyed a red-hot decade-long run on Friends as the fussy domestic diva Monica, Arquette failed to capitalise on the commercial success of the Scream series and the critical acclaim for his 2001 Holocaust drama The Grey Zone.

The couple will reunite on screen in April when Scream 4 is due to hit cinemas.
