Ludacris has denied reports suggesting he was asked to write a rap to help Justin Bieber land a spot in a group freestyle performance at the BET Hip-Hop Awards.

The awards ceremony is famous for its pre-recorded musical segments, known as cyphers, which this year (11) was presented by DJ Premier and featured rappers Eminem, Busta Rhymes, Ludacris and B.o.B., as well as a rhyming Chris Brown.

Earlier this week (begs17Oct11), Premier revealed there was one eager participant he was forced to reject when putting together the rap posse - because the Baby hitmaker wasn't expected to pen his own lyrics.

The producer said, "Justin Bieber even asked if he could do the cypher... But, then we heard, 'He wants Luda to write his rhyme.' I was like, 'Oh, no, no, no, no, no.' If you ain't (sic) writing your own rhyme, you can't do it."

However, Ludacris has now reached out to Premier to clear up the rumours, insisting he was never approached to help Bieber with his punchlines.

In a Twitter.com post, the rapper writes, "My Lil homie @justinbieber loves hip hop & at no point was I supposed to write his cypher flow. #getyafactsright"

And Premier has thanked Ludacris for setting the record straight.

He tweets, "Spoke 2 (sic) @Ludacris & he witnessed Justin Beiber (sic) write his rhymes & that he can flow... He said he wasn't s'posed (supposed) to write 4 tha (for the) Cypher... So shout to @Ludacris for givin' me the correct info."

The BET Hip-Hop Awards took place in Atlanta, Georgia on 1 October (11).
