Singer Miguel gets engaged to longtime girlfriend Nazanin Mandi

Singer Miguel and his longtime gf are engaged after 12 years of dating. Miguel, 30, and Nazanin have been together since he was 18-years-old. A source said:

"Nazanin and Miguel are really excited to get married! They've been together for some time and knew that they were going to spend their lives together," the source says.

"All of their friends and family think they are the best couple and really complement each other."

The proposal, the source adds, was "very heartfelt and real" and "done perfectly." And don't be surprised if the R&B star dedicates a song at his nuptials for his special woman. "Miguel will definitely be singing his soon-to-be wife a tune when their wedding takes place," the source reveals.

Nazanin sparked engagement rumors when she shared a selfie Monday morning and showed off an enormous diamond ring on that finger.

She shared a photo and wrote:
"When you get all dolled up but decide to stay in .... Eat .... And watch A Haunting. Thank you for the Trim @1littlemonster @carltonhairmdr."
