So this is a thing that happened: Aaron Carter professed his love for Hilary Duff. And it wasn't in 2002. He retweeted a pic of Hil and then tweeted, "Don't be that stupid douche that loses the love of your life forever.. Like me...I'll spend the rest of my life trying to better myself to get back to her. I don't care what ANY of you think."

Oooookay, Aaron. Even though Hilary is newly-single after her split from husband Mike Comrie, somehow a reconciliation with the middle school BF who cheated on her with then-rival Lindsay Lohan doesn't seem like the best life choice. But Hilary and Aaron (Haaron?) aren't alone in the "should never (ever) get back together" club.

Here are 9 celebrity couples who shouldn't ever rekindle their former flames.
