Usher and girlfriend Grace Miguel are reportedly engaged.

The 36-year-old singer and 44-year-old manager have been together since 2009.

Miguel has been spotted with a large diamond ring on her left hand at recent events, and a source told Us Weekly she is "happy but they're trying to keep it quiet."

"The Voice" coach and personal stylist Tameka Foster were married from August 2007 to November 2009, and have two children together, 7-year-old Usher Raymond V and 6-year-old Naviyd Ely. Miguel has one daughter, Leaf, from a previous relationship.

"I have an incredible partner and manager," the singer said of Miguel to Billboard magazine in October 2014.

"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."

Usher released his seventh studio album, Looking 4 Myself, in June 2012, and is currently working on new record UR. He debuted as a coach on "The Voice" in 2013, and returned for Season 6 in 2014.
