Beyonce wears a custom, hand-beaded one-piece by Ralph & Russo with Stuart Wieztman shoes for her Mrs. Carter Show World Tour performance at the Ziggo Dome in Amsterdam.

Beyonce and Jay-Z are expecting their second child together, E! reports, citing unnamed sources.

The 31-year-old singer stoked speculation that she could be pregnant with baby No. 2 after canceling a tour date in Antwerp, Belgium, earlier this week because of "dehydration and exhaustion."

Beyonce gave birth to the couple's firstborn, daughter Blue Ivy, in January 2012, spurring a media frenzy not seen since Brad Pitt and Angelina Jolie's twins arrived in July 2008.

On May 6, the Grammy-winning diva walked the red carpet at the triple-VIP, punk-themed Met Ball in New York City wearing a glamorous empire-waist Givenchy gown with a distracting design atop the bump area.

Her Mrs. Carter World Tour -- which kicked off last month in Belgrade, Serbia -- closes Aug. 5 at the Barclays Center in Brooklyn, Jay-Z's hometown.

A rep for Beyonce could not immediately be reached.
