Rebecca Loos is worried that she will be booed by the Cirque de Celebrité audience when she joins the show tonight.

Loos has been recruited as a replacement for ex-Boyzone singer Shane Lynch, who pulled out due to an injury. Big Brother 8 contestant Liam McGough is also joining the show.

Rebecca was unpopular with X Factor audiences when she appeared on a celebrity version of the talent contest in 2006.

A source told the Daily Star Sunday: "She didn't get a good response on X Factor and is petrified that she will be greeted with jeers tonight."

Loos has appeared on a number of other reality shows since claiming that she had an affair with David Beckham in 2004.
