Two of Ireland’s top models will fight to the death in an exclusive live bout on TV3 this weekend.

Rosanna Davison, son of nanny shagging crooner Chris de Burgh, and Glenda Gilson, of no esteemed parentage whatsoever, will battle it out in a caged arena at Dublin’s O2. The pair have been at loggerheads since one of them went off somewhere with the other one’s elderly property developer and extremely wealthy man friend.

The drama has been built up by the Irish Independent in a series of increasly mawkish articles in which both ladies weep as they are being interviewed, trying to elicit sympathy from the general public who seem blind to the fact the whole thing is a ridiculous publicity stunt to keep two vapid, Z-list celebrities in the limelight.

Head of Sport at TV3, Ashley Grimes, told the Irish Sentinel this morning that they were expecting record viewing figures. “This might seem like something spur of the moment but we’ve done our research. Polls show that 87% of people would enjoy seeing Rosanna having her head caved in by a spiked mace while nearly 98% of people had no idea who Brenda Gilson was but would quite happily watch her being eviscerated by a razor sharp cutlass or have her legs blown off by a blunderbuss.

So, that’s what we’ll do. A selection of medieval weapons will be available to each combatant and the last girl standing wins the prize of a cover shoot for U Magazine, a post dedicated to them on Showbiz Ireland and a complimentary bottle of the finest Aspi Spumanti from Krystle Nightclub”.

Already bookies are making Gilson the clear favourite, suggesting her extra wide shoulders will inflict more damage on her opponent but insiders suggest Davison’s patented eyebrow waggle followed by a crunching headbutt move could make the difference.

The show begins at 10.30pm on Saturday night, hosted by Martin King and DJ Spiral, with an undercard of Nell McCafferty vs Tom Dunne’s Producer and Andrea Roche vs a mirror.
