Cheap Thrills Sia feat. Sean Paul
'Price Tag' star Jessie J gets a telling off for spilling the news that she's a mentor on the show.
Jessie J, with her "tells it like it is" lyrics, will soon be sharing her words of wisdom with The X Factor contestants as Tulisa's partner in crime.
The news about Jessie's new X Factor job came after the singer responded to a tweet asking if the rumours she was joining the show were true.
"I accidentally leaked it," Jessie confessed.
"I wasn't supposed to tweet about it. It was a secret and I got told off."
The 'Nobody's Perfect' star will join Tulisa for the judges' houses part of the show, where she'll help the N-Dubz star pick her finalists.
And Jessie reckons they'll both have plenty of good advice for contestants.
"Me and Tulisa had only met once before, so it was a surprise," Jessie told the Daily Mirror.
"But she's cool and two British girls together will be fun.
"And it will be good to have two different strong opinions coming together."
Jessie J will fit her new X Factor role in around her UK Heartbeat tour which starts in October.
