Beyonce killer platform heels

She can sing, she can dance, and she can even perform a balancing act!

Releasing her inner Sasha Fierce for the day, Beyoncé put her (questionably) best foot forward as she browsed the boutiques of London in a towering pair of not-so-practical Lucite platforms, reports the Daily Mail.

The strappy sky-high heels -- which feature an open toe that exposed her hot-pink pedi -- was part of the superstar singer's casual-chic black-and-white ensemble.

Beyoncé, who wore her honey-highlighted hair flowing in loose curls, has been spending time in London with hubby Jay-Z, who was the headline performer at the Wireless Music Festival in Hyde Park.

During her shopping trip, however, Beyoncé was accompanied by her entourage, who joined the former "Destiny's Child" member as she walked cautiously from her chauffeur-driven car to the shops.

At one point during her excursion, the fashion-and-bedding mogul was spotted teetering into designer shop Browns, but she exited empty-handed.

Hmm... perhaps she was searching for blister pads?
