Wedding bells could be in Miguel's near future as reports are surfacing that he and his longtime girlfriend Nazanin Mandi are engaged.

The model/ singer -- who has been dating the Wildheart crooner for more than a decade -- flaunted a shimmery rock on her ring finger in an Instagram photo posted Monday (Jan. 11) with the caption, "When you get all dolled up but decide to stay in .... Eat .... And watch A Haunting."

A source tells E! News, who first reported the engagement, "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."

Miguel's 'Wildheart' Debuts at No. 1 on R&B Albums Chart

Last May, the 30-year-old singer -- who landed his first No. 1 on the R&B Albums chart last year with his third studio album Wildheart -- stopped by Hot 97's Ebro in the Morning and discussed why he hadn't asked Mandi to tie the knot.

"Now, people throw around things like marriage, I just wasn’t raised like that,” he said. "I don’t feel the pressure because I know that when I commit, I really commit."

Miguel also admitted, "I really am wild hearted. That just means I follow my instincts. She's learned that and she's had to adjust, embrace and I love her more for that."
