Rap duo M.O.P. have filed a copyright infringement suit against the WWE and wrestler John Cena's use of their 2000 track "Ante Up."

According to documents obtained by TMZ, the duo -- consisting of Bill Danze and Lil Fame -- claim that portions of their track are samples on John Cena's theme song "The Time Is Now," which is played when he enters the ring and was included on his 2005 debut album You Can't See Me.

In court documents, M.O.P. claims that the words "BRRR Abado" uttered on their song are sampled three times during Cena's theme song -- during the introduction, the second chorus, and third chorus -- without permission.

Furthermore, they allege that the defendants -- WWE, John Cena, and Columbia Records -- were aware from the beginning that they needed to obtain a written license to sample their material, even sending a request, but M.O.P. denied their request. Still, they used the sample.

They claim that WWE's lawyers have said that someone signed off on the license, but it was a receptionist who had no authority to do so.

M.O.P. is seeking damages of more than $150,000, a percent of the royalties including sales of digital downloads, and attorney's fees.
