Wiz Khalifa didn't brush his teeth before he proposed to Amber Rose.

The rapper - who asked Kanye West's ex-girlfriend to marry him on March 1 - admitted he gave Amber ''the real'' him when he asked for her hand in marriage, even avoiding washing.

Speaking on New York radio station Power 105's 'The Breakfast Club', he said: ''Real simple. It was in the morning time. I just rolled out of bed and got The Ring out of the laundry room. Didn't brush my teeth. I was sober, I gave her the real me.

''I didn't cry. But she was crying so much she didn't know what to do. I was like, 'Say something, yo! I didn't let her take time to think about. Knew she was going to say yes.''

Wiz claimed the couple are the ''best of friends'' and ''grew'' into each other.

He added: ''It was just undeniable. None of my family had a problem, just people who don't know us. I never even looked at what people were talking about. I was only concerned about me and her. That just grew. We're the best of friends. We just know more about each other. We just know each other.''
