That look tracksuits you Rosanna.
ROSANNA Davison makes her most dramatic transformation to date - from a Miss World beauty to a down-market skanger.
But even dressed in a garish tracksuit top, Burberry skirt and draped in cheap jewellery, the 26-year-old model still looks absolutely stunning.
And her boyfriend Wesley Quirke even cut an impressive chav double when he pulled on a white tracksuit, Celtic shirt and gold necklaces for the themed party.
The pair pulled on the outlandish gear for a birthday bash being staged by Wesley's brother Andy at the family's Foxrock home.
And they even tucked into cheap take-away food and drank cans of Dutch Gold to carry off the theme to perfection.
One reveller revealed: "It was probably one of the craziest parties ever staged in Dublin - and there was Miss World right in the middle of it.
"Rosanna had a ball and entered into the spirit of the whole night.
"She still looked pretty hot even when she dressed as a chav.
"She drank a few beers and hit the dance floor and she even got stuck into the take-away.
"It may have been a far cry from her posh upbringing but she had a great time."
Rosanna, who is the daughter of Lady In Red crooner Chris de Burgh won the Miss World competition in China in 2003.
She has been dating Wesley for several years. They split up briefly last year but recently rekindled their romance.
