Eva Longoria has surprised shoppers at Victoria Beckham’s London store by swapping the TV cameras for the till.

Victoria posted a picture on her Instagram page of the former Desperate Housewives star working as a sales assistant at her flagship Dover Street store.

“I have a new sales assistant at #VBDoverSt Thank you @evalongoria and @kenpaves X vb,” Victoria posted.

The actress, 40, wore her hair up in a top knot and donned a pair of flashy aviators, but stuck with the all-black uniform as she lent a hand ringing up a white outfit.

Eva and Posh have been BFFs for years and were joined in store by celebrity hair stylist Ken Paves.

The trio continued to joke around outside, with Eva posing up a storm with her impressive yoga moves in front of the shop’s front window.

“The ballet has come to#VBDoverSt London! Starring@evalongoria X X vb,” wrote Posh, as she captured the playful moment.

Victoria has made a name for herself as a fashion designer – but there’s one person who has been burned by the family’s sartorial prowess.

Brooklyn Beckham posted a moody snap last week with the caption: “Rocking the old school Ralph Lauren.”

But dad David was quick to embarrass him by replying underneath: “That’s my jumper.”
