Linda Hogan -- Arrested for DUI

Linda Hogan was arrested yesterday in Malibu on suspicion of DUI ... TMZ has learned.

Law enforcement sources tell TMZ, Linda -- real name Linda Bollea -- was arrested at 1:34 AM Thursday morning and taken to a nearby police station where she was booked and put behind bars. According to the citation, her blood alcohol level is listed as .084, barely above the legal limit in California (.08).

The 53-year-old was released several hours later on $5,000 bail.

An inmate information operator at the jail tells us, she was also booked for driving on a suspended license.

A rep for Linda tells TMZ, Linda sincerely regrets the arrest. The rep claims Linda was on her way home from a jewelry function in L.A. where she drank a glass of champagne on an empty stomach -- in combination with antibiotics that exacerbated the effects of the alcohol. The rep insists Linda was NOT booked for driving on a suspended license.

The rep says Linda was initially pulled over for speeding. It's unclear if Linda was the only person in the car at the time of her arrest.

It's been a rough week for the Hogan family. Linda's ex-husband Hulk Hogan is currently in the middle of a sex tape scandal after footage was released on the Internet yesterday.
