Dated: 2007

This couple is such a strange combination that we're even baffled by the logistics of their brief relationship. How did they meet? Who initiated it—the steroid abusing cyclist or the pixie-like child star? What was his pickup line? "Hey sexy, I thought you were hot in that role on Full House"? Or: "I lied my way into winning a shit ton of trophies. Wanna feel my thunder thighs?"

The age difference between these two is just the tip of the strangeness. He's a now disgraced athlete, she's a tiny mogul who grew up starring in movies about dolphins and moral dilemmas like whether to tattle on her siblings. She embodied boho-chic for a time; he prefers spandex. WTF?
