Congratulations to Miguel and Nazanin Mandi! The "Adorn" singer is tying the knot with his girlfriend of 12 years.

Mandi shared a photo of herself with a diamond ring on her ring finger on Monday (Jan. 11). And a source told E! News that the two are getting hitched.

“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,” said the insider. “All of their friends and family think they are the best couple and really complement each other.”

In an interview with Hot 97's Ebro in the Morning, Miguel also spoke about his budding relationship with Mandi, who he's been with since he was 18.

“I don’t feel the pressure because I know when I commit, I really commit. Now it’s just thrown around because you can easily break up, and I’m not that kind of person,” he said. “I wouldn’t do that to her, and that’s not how I was raised. I don’t think that would be honorable.”

It seems they couldn't be happier either as the two headed to the Dominican Republic last week for some adventure as they laid by the beach and went riding on ATVs. The trip didn't go without some bumps in the road though.

"... I feel like we've been on Survivor for a week, ... & we survived," wrote Mandi in an Instagram post. "From waking up with a Gecko to ending up in a DR emergency room we did THAT & I wouldn't want to take this adventure with anyone else."

Congratulations to the happy couple!
