R&B singer Usher is facing plagiarism allegations once again. This time, he is accused of ripping off a cartoon.

According to DJs in the US, the similarities between Usher's song OMG and a Christmas Carol sung by Homer Simpson are too much to ignore and have created a mash-up of the two songs to expose the alleged plagiarism.

Usher's song, which features will.i.am from the Black Eyed Peas, includes the lyrics: Honey got a booty like pow, pow, pow. Honey got some boobies like wow, oh wow."

The lyrics in Homer Simpson's song, featured in the 2003 episode Dude, Where's My Ranch?, go: "Christmas in December, wow wow wow. Give me tons of presents, now now now...

Gossip sites and fan forums are buzzing over the allegations.

'I bet Usher has more important stuff to do then watch a seven year old Simpsons episode and think, 'That'd be a great song!'' News.com.au quoted Usher fans as writing on the Entertainment Weekly website.

This is not the first time Usher has faced plagiarism allegations. Last month, Wadena Pyatt accused the R&B singer and his collaborator Alicia Keys of stealing her song Caught Up and is seeking damages.

A group founded by George Clooney is collaborating with Google, a UN agency and anti-genocide organisations to launch satellite surveillance of the border between north and south Sudan to try to prevent a new civil war after the south votes in a secession referendum next month.

Organisers said the actor's Not On Our Watch is funding the start-up phase Satellite Sentinel Project, reports the Telegraph.

The project will collect real-time satellite imagery from Sudan and combine it with field analysis from the Enough Project and the Harvard Humanitarian Initiative. It will point out movements of troops, civilians and other signs of impending conflict.

The UN Operational Satellite Applications Programme and Google will then publish the findings online. The groups hope that early warnings will reduce the risk of violence.

'We want to let potential perpetrators of genocide and other war crimes know that we're watching, the world is watching,' Clooney said in a statement.

'War criminals thrive in the dark. It's a lot harder to commit mass atrocities in the glare of the media spotlight,' he added.
