Usher has been accused of ripping off cartoon character Homer Simpson in his smash hit 'OMG'.
The 32-year-old singer has angered fans of popular US TV show 'The Simpsons' with lyrics that sound familiar to a Christmas tune the cartoon dad once sang.
In his smash hit 'OMG', Usher sings: "Honey got a booty like pow, pow, pow. Honey got some boobies like wow, oh wow."
'Simpsons' fans say the line bears too much resemblance to a song Homer sang in a 2003 episode called 'Dude, Where's My Ranch?' which goes: "Christmas in December, wow wow wow. Give me tons of presents, now now now."
A video mash-up of the songs has appeared on YouTube after the similarities were discovered by a US radio show and many people have been commenting on the clip which has received almost 500,000 hits.
One written by jvmiam wrote: "If this is an Example of Usher's so-called talent, it is pathetic. Homer Simpson has more musical ability than Usher."
However other users of the website have said the similarity is pure coincidence.
Usher fan atkinsbabe said: "doesn't matter. 'OMG' is still a great song. (sic)"
