Stealing the spotlight - By Iona Kirby,3rd March 2012

She has been voted the sexiest swimsuit model in the world by Playboy magazine.

And as Joanna Krupa is so used to showing some skin, she couldn’t resist slipping on a sexy number to attend a premiere in Miami.

The Polish model flashed a significant amount of flesh to walk the red carpet at the opening of Mariachi Gringo at the Miami International Film Festival.

The sexy blue backless gown also boasted cut-out sides and a plunging neckline, leaving little to the imagination.

The 32-year-old blonde posed on the red carpet alongside her younger sister Marta, who is also a model.

They cosied up with Real Housewives of Miami stars Marysol Patton and her husband Philippe Pautesta-Herder at the event last night.

Joanna’s dress resembled those she was seen wearing during her stint on Dancing With The Stars.

The model was paired with Derek Hough and the duo came in fourth place in season nine of the hit celebrity dance competition.

Animal lover Joanna has stripped naked to appear in several adverts for PETA.

One of her four campaigns caused controversy when Joanna posed with just a cross to cover her modesty in a bid to encourage the public to adopt dogs.

The model is depicted as an angel floating into a church which is filled with dogs, and the advert has the caption: ‘Be an angel for animals. Always adopt. Never buy.’

Joanna is currently a host and judge on Poland’s Next Top Model, which is due to air its third season in the autumn.
