Jordin Sparks and Jason Derulo constantly talk marriage

Pop star Jordin Sparks and her boyfriend Jason Derulo talk marriage "multiple times a day", despite only dating for less than a year.

The couple went public with its romance in September (11) when the singers stepped out together for Derulo's 22nd birthday party in Hollywood, and now American Idol winner Sparks reveals they are getting serious about their future together.

The 22 year old tells New York radio station 92.3 NOW, "If I'm going to be completely honest, (marriage) comes into conversation multiple times a day... We talk about the future and it's not a conversation that scares us."

However, the No Air hitmaker insists they are too busy to walk down the aisle in the immediate future: "There's a ton going on, (so) not anytime soon, but it's one of those things that we have discussed."
