What a rock!

Rick Ross and 21-year-old girlfriend Lira Mercer are engaged, E! News has confirmed.

The 39-year-old hip-hop mogul has not commented. Mercer posted on her Instagram page late on Thursday a photo and video of the glamour model's giant, sparkling eternity ring featuring an enormous emerald-cut diamond, alongside a larger diamond eternity band, writing, "Forever yours" and "Thanks @rafaelloandco for making everything EXTRA special! #Mrs."

"Happiest Day of my life," she tweeted.

She also posted pics and videos of herself wearing her ring on her Snapchat, at home and in the car, as well as a pic of her "late night dinner" for her "fiancé."
