Flo Rida may have a Top 10 hit with "My House" right now, but the rapper is facing a legal battle after sending an "obnoxious" entourage to a charity event that he signed up to attend.

According to THR, Flo Rida is being sued for $390,000 by City Project Gala after he failed to show up to a "black tie social event" at the Playboy Mansion following the GRAMMY Awards on Feb. 15. The lawsuit, filed Mar. 25 in L.A. Superior Court, claims breach of contract after Flo did not show up at the event but sent his rowdy entourage in his place.

The suit claims that the entourage was "loud, obnoxious … and physically assaulting other guests." The charity event, which benefited Community Inspiring Today's Youth and other organizations, was attended by Diddy, Buzz Aldrin and Jane Seymour, among others.

Dr. Dre was initially named alongside Flo Rida in the suit, but was voluntarily dismissed after he argued that he never signed a contract.
