X Factor twins John and Edward Grimes to perform Ghostbusters

Jedward's mentor Louis Walsh admitted he doesn't believe they will be crowned the winners

Irish X Factor hopefuls John and Edward Grimes will be performing the Ghostbusters theme song on Saturday night, it can be revealed.

The Dublin duo — dubbed ‘Jedward’ — have another no-holds-barred production prepared for the show's themed Movie Night.

While the majority of other contestants have opted for big ballads to show off their vocals, the fun-loving 18-year-olds have once again chosen to stand out from the crowd and hit the audience with an energetic, fast-paced song.

Although the pair have become the most talked-about contestants this year, the show's latest reject, Rachel Adedeji (17), has placed the blame on Jedward for turning the show into a “popularity contest” and not giving other singers a fair chance.

Rachel was voted off on Sunday's show after being placed in the bottom-two for the third time since the live finals began.

However, the aspiring songstress believes she has the talent to go further and it was John and Edward who turned the competition into a “popularity contest”.

“Maybe the public are looking for something different this year,” she said.

“If I had a twin sister with wacky hair maybe I'd still be in. People might like that.”
