Rick Ross is officially off the market.

Lira Mercer, the rapper’s 21-year-old girlfriend, showed off her new diamond ring on Instagram Thursday – with pal Amber Rose later congratulating the pair on their engagement in her own post.

Ross, 39, has yet to comment on the news himself.

The pinup model shows off her enormous bling in one photo captioned, “Thanks @rafaelloandco for making everything EXTRA special! #Mrs.”

In a another post shared just an hour later Mercer flaunts her rock, this time in a video captioned “Forever yours.”

Friend of Mercer, Rose, congratulated the couple by sharing photos from Snapchat on her Instagram.

“Congrats to my girl @lira_galore and @richforever. Love is a beautiful thing,” Rose captioned the side by side photo of the bride-to-be’s ring.
