Oh, this isn't good. Heather Locklear was arrested over the weekend on suspicion of driving under the influence in Montecito, Calif., according to the Los Angeles Times.

Locklear, who turned 47 years old last week, was arrested by the California Highway Patrol -- hey, CHiPs! -- after someone called 911 to report a woman driving "erratically."

Define "erratic"? Locklear reportedly drove "back and forth over a pair of sunglasses on the pavement and revving her engine. After leaving the parking lot, she stopped her car on the street and stumbled into the traffic lane, according to the caller, who followed Locklear out of concern," the Times reports.

Locklear was tested for alcohol consumption, but the tests were negative. Results are pending on other drug tests.
