Demi Lovato Calls Simon Cowell ‘Grandpa’ During First ‘X Factor’ Audition (EXCLUSIVE DETAILS)

Brit's 'X Factor'!
Britney Spears will be a judge on the reality competition!
There’s chemistry.

New X Factor judge Demi Lovato called out her boss, show creator and fellow judge Simon Cowell, for being over the hill during her and Britney Spears’ first round of auditions in Austin, TX, on Thursday.

“Within a few minutes of judging starting, Demi called Simon ‘grandpa’ because he’s seemingly decided to play the role of Cupid for her,” someone in the audience told Celebuzz.

The 19-year-old’s ‘grandpa’ jab was in response to a comment from Cowell, 52, who told one contestant whom he identified as “cute” that the former Sonny with a Chance star was “single at the moment.”

“Demi thought it was funny and she was laughing at Simon,” said the onlooker, who added “the contestant looked a bit nervous, because as it turned out his girlfriend was in the audience.”

Our spy also tells us 30-year-old Spears — who reportedly signed on to the Fox show in a deal worth up to $15 million — took to the judges’ table “like a duck to water.”

“She is already backing one group who she likened to the Dixie Chicks,” the insider added.
