Singer-turned-fashion designer Victoria Beckham enlisted her actress friend Eva Longoria to work behind the tills at her London store over the weekend (28-29Nov15).

The former Spice Girls star unveiled her newest staff member at the Dover Street branch of her Victoria Beckham brand by posting a picture on Instagram.com.

In the shot, Eva can be seen wrapping an item of clothing for a customer, and working alongside several other members of the store's team.

"I have a new sales assistant at #VBDoverSt Thank you @EvaLongoria..." Victoria tweeted.

The singer went on to add a picture of Eva joking about in front of the store's front windows, adding, "The ballet has come to #VBDoverSt London! Starring @evalongoria..."

Eva also tweeted about her work experience, writing, "Landed in London and first stop... @victoriabeckham #DoverSt..." before reposting Victoria's pictures.

The former Desperate Housewives actress is in Britain to give a talk at Oxford University on Monday (30Nov15) ahead of hosting her annual Global Gift Gala charity event in London that night.
