Hinting much? Young lovebirds Jason Derulo and Jordin Sparks didn't shy away from hiding their affection for each other in Derulo's "Marry Me" music video in 2013. In the footage, Derulo is seen shopping for an engagement ring, kissing Sparks in bed, and popping the question to his bride-to-be. "We'll forever be in love so there's no need to rush," the singer serenades Sparks. "But one day I won't be able to ask you loud enough -- I'll ask you, 'Will you marry me?'"
