Rihanna's representatives have shot down reports the pop star has recorded a new song blasting ex-boyfriend Chris Brown - insisting the recording appearing on Kanye West's blog is a fake.
The Umbrella hitmaker was said to have laid down vocals on a new track, titled Silly Boy, in which she seemingly mocks her former lover over their infamous bust-up in February (09), which allegedly left the star battered and bruised.
The song, which also reportedly featured guest vocals from Lady Gaga, was posted on West's internet blog at the weekend (09-10May09).
The track contained the lyrics, "Silly boy get outta here, I don't want you any more, the only thing I want from you is to stay away. I said I'm not coming back, you fooled me once but you can't have that ego turning. Just too bad for you, that when you had me, didn't know what to do, she's over you.
"Cause you had a good girl, good girl, girl. That's a keeper. You had a good girl, good girl but didn't know how to treat her."
But representatives for both artists have denied the pair had any involvement in the song.
Rihanna's camp insist she is not on the track, while the Poker Face star's spokesperson tells Access Hollywood, "The song is a fake It's not Lady Gaga."
Brown is facing assault charges over the alleged attack. He denies charges of felony assault and making criminal threats. If convicted, he faces almost five years behind bars.
