The couple, who have been dating since 2009, shunned the whole big white wedding thing for a secret ceremony apparently, and enjoyed a honeymoon in Cuba.
Last week Grace shared a photo collage of her and her reported new husband sightseeing in Cuba, and yep, there's a shiny gold wedding band on Usher's finger. Aww.
The I Don't Mind singer and Grace sparked engagement rumours back in January this year when she was spotted sporting a dazzling diamond ring on her left hand, however the pair never confirmed the news.
Now sources have told Us Weekly the two secretly tied the knot over America's Labour Day weekend (4 - 7 September) before jetting off to Cuba for a romantic honeymoon.
One source revealed the couple originally planned to tie the knot in front of around 100 guests in Atlanta, Georgia, but opted to elope instead. Let's hope no-one bought a new hat in anticipation!
Speaking to Billboard in 2014, Usher said: "I have an incredible partner and manager.
"She has helped me through some of the hardest times in my life and my career."
Usher and Miguel started dating shortly after the singer split from his first wife, Tameka Foster, in 2008.
