Don't be fooled: Karen Koster is the 'dark horse', according to her TV3 colleagues

A Brush With Glory: Fashionista Karen Koster who is style ambassador for Hermans

The TV3 hosts will compete with each other in a Celebrity game show to win money for their chosen charity.

This weekend’s 'Crossfire Celebrity Special' will see Xposé presenter Karen Koster, Ireland AM host Sinead Desmond, Midday host Elaine Crowley and Midweek reporter Ciara Doherty battle it out to win up to €2000 for their chosen charity.

The TV3 beauties undergo the pressure of three fast-paced general knowledge rounds with host Sean Moncrieff firing questions at them.

Over the course of the programme, the four women will compete to force each other out of the game.

They must get their answers correct in order to attack the opposition.

With the gloves well and truly off, will the TV3 sisterly bond be crushed as Karen, Sinead, Elaine and Ciara go head-to-head?

Elaine, Ciara and Sinead think that bubbly, blonde Karen is the dark horse of the competition.

Sinead was quick to dub the Xposé presenter as the winner, quipping to Sean, “Don’t be fooled by the lip gloss and the blonde hair, big brain there!"

Midweek’s Ciara also had similar thoughts on Karen: “I don’t want to give her a big head but I think you’re trying to hustle people, Karen!”

Tune in this Saturday 2nd August at 7.15pm to see which TV3 beauty will come out on top?
