R&B star Miguel is engaged to his model girlfriend Nazanin Mandi .
On Monday (11Jan16), the Adorn singer's longtime love sparked speculation she is heading down the aisle by posting a selfie on Instagram.com, subtly showing off what appeared to be a massive diamond engagement ring on her left hand.
A source tells E! News the engagement rumours are true, and that 30-year-old Miguel's proposal was "very heartfelt and real" and "done perfectly".
The insider adds, "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... All of their friends and family think they are the best couple and really complement each other."
