Susan Boyle, the surprise singing sensation who took the world by storm, will appear on the live shows in the next few weeks.

Susan found fame after entering Britain’s Got Talent earlier this year, and amazed millions with her stunning voice and contrasting appearance.

Now the Scottish star will appear on The XFactor – her first live British TV performance since being discovered.

It makes perfect sense and will create a big buzz,’ says a backstage source on the show.

‘There are two shows to fill on Saturday and Sunday nights, so they’re also planning guest appearances from previous winners and runners-up, as well as celebrity guests,’ the source told The Mirror.

Susan sang at the finale of America’s Got Talent last month and is set to appear on X Factor in November.

Her new album I Dreamed A Dream is also due out next month.

Other stars rumoured to perform on the first live X Factor shows are last year’s winner Alexandra Burke, Robbie Williams and soul diva Whitney Houston!

X Factor judge Cheryl Cole – who has her first solo single out – is also lined up to sing on the show.
