The 'Roll Up' hitmaker confirmed the exciting news earlier this evening (March 1) after posting a photo, originally sent to Instagram, of Rose's hand adorned with a beautiful ring and he accompanied the picture with a simple caption that read: "She said yes!!!"

The pair have been together for a while now and Rose, who previously dated rapper Kanye West, took to her own Twitter page tonight where she added: "He has made me the Happiest Woman in the World!!!!"

Rose recently spoke to Billboard's The Juice column and explained that she is very much in love with Khalifa and they "will get married" when their schedules allow the time:

"We [Wiz Khalifa and I] are very much in love and we're really, really busy. He [Wiz Khalifa] is in LA working on his album. I'm in NY working on my album. We travel a lot, separately. We do want to get married and  will get married. But we want to get married, enjoy each other, have babies and be able to take time off. We'll get married when things calm down a little bit."
