Heather Locklear was arrested this week on charges of driving under the influence after police said the 47-year-old actress was driving erratically while leaving a parking lot. A witness told police that Locklear “was revving her engine loudly, and backed over a pair of sunglasses several times,” said a California Highway Patrol spokesman. Officers found her nearby, parked in the middle of a highway. Police said Locklear appeared to be “under the influence of prescription medication.”
