Victoria Beckham took to social media to show off her less serious side, and the impressive results of her ballet regime as she displayed her physical flexibility in an unbelievable Instagram post.

With her legs opened further than a 90 degree angle as she reclined casually on a luxurious sofa in a hotel room, she took the photo behind the scenes at her new fashion shoot for Vogue on Thursday (March 31st).

The 41 year old mother of four wrote to her 9.7 million followers: “It's amazing what you can do in culottes… those ballet classes are paying off! Thank u @edwardbarsamianand @voguemagazine! Kisses from LA x vb.”

The Spice Girl turned fashion designer was initially reluctant embrace the social media revolution, but has increasingly taken more pictures of her day-to-day life as a mother rather simply using her Instagram as a vehicle for her business interests, dispelling the widely-held belief that she’s a kind of humourless robot.

It’s the twentieth anniversary of the Spice Girls’ debut single ‘Wannabe’ in 2016, and rumours of a reunion have abounded for several months now. While the other four members – Mel B, Mel C, Geri and Emma – are on board, Victoria is the only one holding out on a full reunion as talks go on.

Recently, Mel B told a Digital Spy podcast that she thinks Victoria isn’t too friendly. “She's just a little bit of a b***h to people,” she said. Quickly rowing back on that suggestion, she added: “but she's very down to earth, with a great sense of humour… I think between the five of us, we're all b***hes.”
