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."
