Socialite and model Amber Rose confirmed on Sunday, at 2012 Grammys, that her rapper boyfriend Wiz Khalifa had not proposed to her.

"We're not engaged. Not yet," E! News quoted the 28-year-old as saying. Her 24-year-old rapper boyfriend clearly had a little inside information though. According to him, they could be engaged very soon.

"Not yet, but soon though," Khalifa added, also according to E! News.

"We want to get married. We're just taking our time. Whenever he wants to propose, that's when it will happen," quoted Rose as saying, and adding, "He's just the sweetest guy. He's very normal. He didn't let the fame and everything get to him."

Rose, looking mesmerizing in a yellow Versace dress, showed up at Sunday's Grammys with Khalifa, whose song "Black and Yellow" was nominated for two Grammys - "Best Rap Song" and "Best Rap Performance".

The couple started dating a year ago, after Rose gave up her high-profile relationship with another rapper, Kanye West.
