With the Duchess of Cambridge currently out of action, an unlikely philanthropic heroine has stepped into her shoes: Queen B.

We spotted Beyoncé and hubby Jay Z in East London today, paying a visit to a community arts project.

Not that Bey took a leaf out of the royal sartorial charter - she opted for an altogether edgier printed pencil skirt and clashing print top combination, while Jay Z dressed down in a Maison Kitsune sweatshirt.

Having been soujourning in Paris since the end of their joint On The Run Tour last month, the couple hopped on the Eurostar yesterday with daughter Blue Ivy for a flying visit to the capital (which, with the aid of a babysitter, included a night partying at the Dover Street Arts Club last night).

Hopes are high among Team ELLE that we'll run into them on the Tube during our commute home.

We'll keep you posted.
