Rick Ross may be 'Rich Forever,' but the government of Nigeria would like their share.

According to reports, the Maybach Music Group boss has been named in a potential lawsuit filed by the Cross River State Government for breach of contract. The government has sought legal representation in the U.S., to pursue suit against the corpulent MC, after he failed to perform at the Calabar Festival on Monday (Dec. 26), without giving sufficient notice.

In a BlackBerry Messenger broadcast on Wednesday morning (Dec. 28), the government announced the cancellation, citing "reasons unknown" for his unexpected no-show, and claiming the 'Hustlin'' rapper "cancelled his performance at Calabar Festival after accepting a full performance fee."

"The rapper, Rick Ross, has issued a statement cancelling his performance at the Calabar Festival, scheduled for December 28, 2011, for reasons not related to his recent surgery and seizures," the statement explains. "The performer's cancellation is unexpected and the reasons are unknown to Cross River State since he has confirmed receipt of his entire performance fee many weeks ago. Currently, Cross River State and its agents have retained counsel in the United States to pursue their legal and monetary remedies against the artist."

AllHipHop reports that a representative for the rapper "was forced to cancel" his appearance, just days before.

"Rick was very excited to attend this event as it is the biggest festival in Nigeria and he is quite disappointed that he will not be performing," his rep explained.

The rhymer, who just shot a music video with Drake, French Montana, Meek Mill and DJ Khaled for his 'Rich Forever' mixtape, has yet to address the potential lawsuit. His fifth album, 'God Forgives, I Don't,' will be in stores in 2012.
