Singer Pink has gotten engaged to her on-again, off-again boyfriend, motocross champ Carey Hart. (Don't worry, it's not that "Sunglasses at Night" guy.) Pink apparently took matters into her own hands and proposed to Hart herself. At a motocross race in California on Sunday, Pink wrote "Will You Marry Me?" on a pit board and held it up in front of the grandstands during the third lap. After her man kept going, she wrote "I'm serious!" and then Hart pulled off the track and picked up Pink.
