The Odd Couples

Ashton Kutcher and Rihanna, Jennifer Lopez and Casper Smart, & More Odd Celebrity Rebounds (PHOTOS)

While Battleship star Rihanna  denies any rumors that she’s dating Two and a Half Men’s Ashton Kutcher, we can’t help but wonder why she was seen leaving his house this week at four in the morning. Freshly separated from wife Demi Moore, Kutcher doesn’t seem like he’ll be settling down any time soon. But what about RiRi? Having recently been linked to once-abusive ex-boyfriend Chris Brown, the “We Found Love” singer was quick to deny rumors she was seeing Kutcher. But if the late-night visit does indeed turn into something more permanent, it seems like an odd coupling. We take a look at some of the strangest celebrity rebounds.
