The 'One Thing' stars shocked shoppers and employees at the popular retail destination with a surprise gig.

One Direction stars Liam Payne and Niall Horan treated fans to an impromptu acoustic performance at London's Westfield shopping centre yesterday, with pictures and fan-shot videos from their unannounced set cropping up online today (3rd August).

The 'Gotta Be You' singers headed out onto a pop-up stage at the Shepherd's Bush shopping centre on Thursday (2nd August), where they played new versions of some of their biggest hits, including 'What Makes You Beautiful'.

Singer Niall Horan took on acoustic guitar for his and Liam's unplanned set, decked out in a backwards cap, dark shades, a white t-shirt and jogging bottoms.

Fellow One Direction star Liam Payne handled singing duties while wearing a simple grey t-shirt and tracksuit bottoms, as the two thrilled a group of fans who had gathered near one of the centre's escalators.

Earlier this week One Direction's Zayn Malik was pictured out and about in London as he showed off his new longer hairstyle and some designer stubble, while heading out to a nightclub in the UK capital.
