Beyonce raises eyebrows with tour costumes

This year alone, Beyoncé sang for the president, headlined the Super Bowl, scored her 17^th Grammy, debuted a highly rated HBO documentary and was named half of pop music’s first billionaire couple (with hubby Jay-Z). So what does such an accomplished woman wear to launch her latest world tour?

The answer, in a gold-plated nutshell, is whatever she wants. And she did.

Beyoncé kicked off “The Mrs. Carter Show� tour Monday in Serbia, and the pop diva donned some daring attire.

PHOTOS: Beyoncé and Jay-Z through the years

Photos that hit that net – and have tongues wagging – show the singer in a number of barely there numbers including a white sheer mini skirt, a handful of edgy cat suits, and a low-cut full-length blue sequined cat suit (the shade of blue reminds Pop & Hiss of Pepsi, which the singer struck a $50 million deal to hawk).

But the outfit that’s getting the “Bootylicious� singer the most ink: a gold-sequined bodysuit that accentuates her famous curves. Pretty tame, until you peek at the singer’s chest and notice the outfit is bedazzled with sparkly, er, erect nipples -- Ooh là là!

Beyoncé’s trek -- her first both since 2009 and since giving birth to daughter Blue Ivy last year -- and her glittery assets travel through Europe this spring before opening in the States with a show at Staples Center on June 28.
