One more and it's a trend! Beyonce sported faux nipples for a second time, debuting a new costume during an April 18 concert in Croatia. For the second night of her just-launched Mrs. Carter World Tour, the stunning singer, 31, wowed fans in a long-sleeved "regal-inspired" gold embellished bodysuit by Ralph & Russo -- featuring gold crystal and bullion thread embroidery and stylized gold nipples.

This particular number is certainly more demure than the gold bodysuit that the "Grown Woman" singer rocked for the tour opener in Serbia on April 15: The bedazzled, long-sleeved, fringe-lined numbered featured a pair of painstakingly articulated faux breasts and nipples.

With footwear exclusively designed by Stuart Weitzman, Beyonce is donning tour costumes created by a slew of designers, including Emilio Pucci, Peter Dundas, Julien McDonald and Dsquared2.
