The two have been together since his divorce from former wife, Tameka Foster in 2009.
While the two are known to be terribly private about their relationship (who can blame them?) he opened up about the love of his life to Billboard magazine in 2014 “"I have an incredible partner and manager. She has helped me through some of the hardest times in my life and my career. She's someone who's been able to support and understand all of who I am. Not just as a dancer or as a performer or as a singer, but as a humanitarian and a business man and as a person,” the 36 year-old said.
While there hasn’t been a formal announcement, Grace has been seen publicly sporting the impressive rock.
Congratulations are certainly in order!
