Bad things come in threes, right? We bet David Cassidy agrees: This week, the onetime teen heartthrob was arrested on his third drunk driving charge. Yikes!

TMZ reports that Cassidy, dad to actress Katie Cassidy, was pulled over on Friday night after making an illegal right turn. Cops said they smelled booze, so he was given a Breathalyzer test -- and he bombed it pretty badly, blowing a 0.19 -- over twice the legal limit.

Cassidy was taken to jail and booked for driving under the influence, then released a short while later. But he'll probably be back behind bars soon enough. Why? Cassidy was arrested for a DUI in 2013 and also in 2010. Since this is his third offense, TMZ notes that he's probably facing jail time.

Here's hoping Cassidy is brought to justice -- and that he gets help if he needs it. Drunk driving is serious and dangerous, and it needs to be treated as such.
