Heather Locklear’s arrest came out of nowhere! We’ve been having plenty of fun-filled weekends lately, this time thanks to Heather’s “erratic” driving and a concerned citizen who reported it to the California Highway Patrol.

People reports that Heather was spotted “back[ing] over a pair of sunglasses several times” and later “stopp[ing] on a nearby highway, exiting her vehicle” on Saturday evening. But this was no run-of-the-mill potential DUI, because “alcohol was ruled out as a factor.” Police suspect that prescription medication caused Heather’s erratic behavior, and she was booked at 7 p.m. at a local jail.

After her slightly crazy-looking mugshot, Heather was released without bail.
