Although Bieber made his crush on this Pussycat Doll known while they recorded "We Are The World," Scherzinger reciprocated his sentiment by admitting that he made her blush and tweeting at the mini Casanova that he was "cute" too. Kudos to J.B. for milking his puppy dog eyes and childlike charm, which will continue to work if his career goes more "Justin Timberlake" than "Aaron 'Creepy Flesh Beard' Carter."
