Pop superstar Beyonce is continuing to titillate fans on her world tour after showing off another saucy bodysuit featuring fake nipples as she performed in Croatia on Wednesday night (17Apr13).

The Crazy in Love hitmaker shocked fans as she kicked off The Mrs. Carter Show trek in Belgrade, Serbia on Monday (15Apr13) when she donned a headline-grabbing gold glitter costume, designed by The Blondes, which featured the emphasised outline of breasts, complete with faux nipples.

She switched up her stage outfits for the second date on her tour in Zagreb, Croatia and replaced The Blondes one-piece with an embroidered, gold leotard by Ralph & Russo, which was also adorned with fake nipples.

Beyonce, who also sports costumes created by fashion icon Julien MACdonald, Emilio Pucci and DSquared2 during her live shows, will continue on the European leg of her tour until the end of May (13), before returning to North America.

Meanwhile, the beauty has recruited rising R&B singer Luke James to support her on select European dates - he will open for Beyonce from 24 April (13), when she hits the stage in Paris, France.

Announcing the news, Beyonce says: "Luke James is a gifted singer and songwriter and what he does on stage with his pure falsetto is incredible.

"I am excited to have him join the tour and to introduce this soulful singer to an audience in Europe that will be discovering a true star."
