Hollywood's hottest coordinating couples

Britney Spears, Justin Timberlake, denim

Rhinestone cowboys

Just call this the most embarrassing fashion moment of Justin Timberlake's life. Whose idea was his and Britney's matching denim duds and dueling bling at the 2001 American Music Awards?

Ironically, today Justin is partners in a cool denim line. And Britney, well, she's not coordinating with anyone right now. Thank god.
