Jordin Sparks attended KIIS FM's 2012 Jingle Ball at the Nokia Theatre in Los Angeles on Monday night, and she rocked a tight red dress at the event.

She brought her boyfriend Jason Derulo and recently opened up about the seriousness of their relationship. The couple has been dating for over a year, so is there an engagement in the future?

She told Life & Style on Dec. 2, "I don't want him to feel pressure and I don't want to be that girl, but I do find myself sometimes going, 'Wouldn't it be great?'"

When the former "American Idol" star promoted her new fragrance, Ambition, at a mall in Chicago over the weekend, she told reporters, "I want to gush about him. I would shout it from the rooftops. He is incredible. I don't mind talking about it."
