Ray J drops x-rated Kim Kardashian diss track

Ray J hasn't held back in a brand new, x-rated diss track aimed at his ex Kim Kardashian.

The singer has teamed up with Chris Brown for Famous - a dig at Kanye West's song of the same name - and delivered a scathing attack on his former flame and her man, who was hospitalised for exhaustion this week.

In a hard-hitting verse, he sings: "She f***ed me for fame, look in her eyes. She was the first one to sign on the line. She was the real one to plan it all out.

"Look at the family, they walk around proud. All because she had my d**k in her mouth."

Last month, Ray J - whose likeness was used as a nude wax figure in Kanye's Famous video - was name-dropped in the rapper's track, and he wanted to have his say.
