In September, Rick Ross put an engagement ring on Lira Galore.

But now it's looking like she won't end up being Mrs. Bawse.

Allegedly, the two had a major blow up and Lira moved all of her stuff out of Ross's mansion.

The MMG boss popped the question to the stripper-turned-Instagram-model-type after only a few months of dating. Galore had been linked to Drake, Meek Mill and Justin Bieber before getting together with Ross.

A couple of weeks ago, the Internet had a lot of fun with old Tweets of Galore flirting with Ross's MMG soldiers Meek Mill and Wale.

There's absolutely nothing linking the break up to this.  But such revelations can't be comfortable for a newly engaged couple.

Anyway, as of yesterday Lira was still flaunting the 350K ring Ross bought her. So maybe there's a chance of reconciliation.
