Bassey relative in 'X Factor' audition

The X Factor judges were left stunned when Dame Shirley Bassey's teenage granddaughter tried out for the show, it has emerged.

Tatjana, 17, performed in front of Simon Cowell, Louis Walsh, Dannii Minogue and Cheryl Cole in Birmingham earlier this year and her audition will be screened later this month, according to The Sun.

A source told the newspaper: "When the judges realised who Tatjana was, they were gobsmacked. They couldn't understand what she was doing on the show.

"It was quite sad. She had to explain that she hasn't seen her gran since she was tiny and admits the reality show is her only chance of a pop career."

It is believed that the audition took a further twist when Tatjana's rendition of Faith Hill's 'There You'll Be' proved to be a disappointment, leaving the panel with a dilemma.

"They weren't bowled over but they did like Tatjana's personality," the insider explained.

The newspaper reports that Tatjana is the daughter of Bassey's adopted son Mark Novak. She is said to have lost touch with the singing superstar after her parents split in the '90s.
