This isn't the first time we've heard about Rick Ross facing legal trouble because he backed out of a concert (not before taking the concert promoter's money, though). The MMG crew aka Rick Ross, Meek Mill, Wale, Stalley and Omarion were all tapped for a huge concert in London, and now all five are being sued for allegedly backing out.

The rap crew was expected to perform at the Wembley Arena in London on September 12th 2012. After the concert promoter advanced the rappers a chunk of their performance fee, Meek attempted to post-pone the concert. They then negotiated another date, but apparently that didn't stick either, and everyone backed out.

Now the concert promoter wants all the money back, including the $93,281.26 he fronted Rozay and friends for their flights and other expenses. If you're curious, see the break-down of each rapper's fee below.

Stalley:  $5,500
Omarion:  $12,000
Wale:  $35,000
Meek Mill:  $40,000
Rick Ross:  $100,000
