Nick showed how sweet he was on Mariah when he popped the question in April 2008. But it wasn't just his proposal: He hid the 17-carat ring in a Ring Pop wrapper! The couple were sitting on Mariah's roof, celebrating her 18th No. 1 hit single, when Nick popped the question. "I opened up a Ring Pop first ... and then I give her one, and she was like, 'It feels like mine is broken,'" he told Oprah Winfrey. "I was just like: 'Let's just open it. It's a festive moment.' And she opened it and her ring was in there." Mariah got flustered and ran away, but she said yes. A few days later, Nick asked again during a helicopter ride over Manhattan, and Mariah confirmed her initial acceptance.
