THOUSAND OAKS, Calif. >> Actress Heather Locklear was released Friday from a hospital after she was treated in the intensive care unit for an unknown ailment.

She was discharged in the afternoon, Los Robles Hospital spokeswoman Kris Carraway-Bowman told The Associated Press. The 50-year-old "Melrose Place" actress was hospitalized Thursday.

The hospital in the Los Angeles suburb of Thousand Oaks said earlier in the day that Locklear was medically stable and being cared for one-on-one in the ICU. Paramedics transported her from her home in Westlake Village, 35 miles northwest of Los Angeles.

Locklear has been hospitalized several times over the years. In 2009, she pleaded no contest to reckless driving after being arrested on suspicion of driving under the influence of prescription medication.

Locklear also starred in such TV series as "Dynasty" and "T.J. Hooker."

Her engagement to "Melrose Place" co-star Jack Wagner recently ended. She was previously married to Bon Jovi guitarist Richie Sambora, and they have a daughter together.
