Jessica Mauboy's latest hit is just a bunch of gibberish

Australian pop star Jessica Mauboy has recorded a version of her upcoming single Saturday Night in a language that virtually no one on the planet understands.

If you think that's weird, international pop sensations Kelly Rowland, Kelis and Flo Rida have also recorded singles in "Simlish", a fake language akin to gibberish spoken by the characters in the popular "life simulation" video game series The Sims.

"The language is combined with Ukraine and Singapore and it's kind of like mushed together," Mauboy said in a phone interview.

"[The song] took a day to learn ... I was so embarrassed at the beginning, I was like 'oh my gosh I can't sing this, I don't know how to sing this', so the other side of me just had to come out and be a little bit humorous with it."

The English version of Saturday Night - or "Surbiduh Nye" in simlish - features rapper Ludacris and is on Mauboy's new album Get 'Em Girls, which will be released on Friday.

The "simlish" songs were recorded to promote The Sims 3 and The Sims 3 Late Night games for the PC, Mac and games consoles. They will be featured in the video games and on publisher Electronic Arts' website, with a potential iTunes release down the track.

Mauboy was the runner-up of the fourth series of Australian Idol in 2006, after which she signed a recording contract with Sony Music Australia.

Her debut album, The Journey, was released in 2007 and soon after she joined the Young Divas, but the group split up in 2008. Her second album, Been Waiting, was released in 2008 and contained her first number one single, Burn
