Congrats to Rick Ross.

The Bawse just put a ring on his girlfriend, Instagram model type Lira Mercer . (Lira Galore to her 2 plus million followers.)

Ross was first spotted with Galore -- who's been linked to Drake, Meek Mill and Justin Bieber -- in April. Things must have progressed quickly between the two because now they are planning their wedding.

Amber Rose broke the news because of course she did.

Check out more photos of the soon-to-be Mrs. Bawse.
