Actress Heather Locklear has checked into a facility for treatment of depression.

The former " Melrose Place" and "Spin City" star is undergoing evaluation at a clinic in Arizona. Her publicist tells the celebrity mags that Locklear, 46, "has been dealing with anxiety and depression."

"She requested an in-depth evaluation of her medication and entered into a medical facility for proper diagnosis and treatment," publicist Cece Yorke says in a statement. "This is a confidential medical matter and no further statement will be released."

In March, paramedics responded to Locklear's home after a 911 caller reported the actress was on the verge of a suicide attempt. Her rep said at the time that Locklear was "fine" and that no one in the house had placed the call.

Locklear recently completed work on a Lifetime movie called "Flirting with 40." Her other recent credits include another Lifetime flick, "Angels Fall," and guest appearances on " Hannah Montana" and "Rules of Engagement."
