Beyoncé Posts Teaser Photos From Mrs. Carter Tour Rehearsal On Tumblr, Reveals H&M Campaign Ads [PHOTOS]

Beyoncé posted teaser pictures on Tumblr of the rehearsal for her opening concert of the 42-city Mrs. Carter Tour. Beyoncé's concert is set to be held in Belgrade, Serbia tonight.

The behind-the-scenes shots of Beyoncé's concert rehearsal show Queen Bey and her backup dancers practicing choreography. In one photo, Beyoncé is shown practicing her signature dance moves in high-heels and a leotard that shows off her curves.

Beyoncé has been in the news constantly these last few weeks. On April 4, Beyoncé debuted a Pepsi commercial titled "Mirrors" in which she revisited her favorite past looks, including the tank-short-combo from "Crazy In Love" and the iconic black leotard and metal glove for "Single Ladies." In the 61-second clip, Beyoncé previewed a small sample from her upcoming single "Grown Woman."

Beyoncé is also participating in a new series of H&M Advertisements for the summer. Last month, fans got a sneak-peek at the new ads featuring Beyoncé lounging on the beach in a low-cut top and short-shorts.

The campaign is entitled "Beyoncé as Mrs. Carter in H&M," and the series of photos was shot by Inez van Lamsweerde and Vinoodh Matadin.

The singer commented on the company and campaign, "I've always liked H&M's focus on fun affordable fashion. I really loved the concept we collaborated on to explore the different emotions of women represented by the four elements - fire, water, earth and wind. It was a beautiful shoot on a tropical island. It felt more like making a video than a commercial."

The campaign will be used in collaboration with her Pepsi campaign and Tumblr teasers to promote Beyoncé's world tour. The full list of tour dates can be found here.
