Rick Ross has reportedly evaded court papers for as many as six months stemming from lawsuit filed by a British concert promoter.

Christian Ezechie, a promoter who says he’s coordinated concerts for artists like Usher, Busta Rhymes, and Missy Elliott, apparently coordinated for Ross, Meek Mill, Wale, and Omarion to perform at London’s Wembley Arena in 2012. Despite their prior agreement, none of the artists in question followed through but received as much as $100,000 in advance payment.

Ezechie filed his lawsuit in a New York federal court in October according to Page Six and has since been unable to get in contact with the defendants to deliver the papers. “Despite numerous and diligent attempts…we have been unable to locate the defendants,” Ezechie said.

Ezechie’s lawyers claim that a registered address for Ross is actually a UPS store and when a process server visited the rapper’s house in Miami he was unable to locate the artist. The court papers also allege that process servers have been “hesitant to serve him while he is surrounded by security guards” during show performances.

“It’s blatant roberry he’s doing, and he’s an artist worth $50 million,” Ezechie says. Page Six’s article reports that the promoter advanced the Maybach Music Group founder $100,000 for the performance and a similar amount for the other associated performers.

Earlier this week, a judge ruled that if the MMG defendants aren’t located prior to a hearing scheduled for early June, Ezechie’s lawyer can begin tracking down the defendants by means such as “posting a notice in a newspaper.”

On May 6, HipHopDX reported that Eminem is slated to be the first rapper to headline London’s Wembley Stadium, a venue located directly next to the Wembley Arena where Rick Ross was scheduled to perform. A week later, it was announced that Odd Future will open for Eminem at the planned July 11 concert.
