Rap mogul Sean 'Diddy' Combs is eager to test his comedy credentials with a cameo role on hit series 30 Rock.

The hip-hop star loves the Tina Fey-created show and has become pals with 30 Rock funnymen Tracy Morgan and Jack McBrayer.

And he's been lobbying the stars for a guest spot on the program.

McBrayer says, "He is a big fan of 30 Rock and he's like, 'Can I be in the show?' and I was like, 'What if we played best friends?'"

Combs has previously showed off his acting skills with roles in 2008 TV movie A Raisin in the Sun, based on the play by Lorraine Hansberry, and a two-episode stint on TV crime drama CSI: Miami earlier this year.
