If it wasn’t for the sunglasses and the scowl, you’d be forgiven for not recognising Victoria Beckham.

The former Spice Girl traded in her signature skinny trousers for a rather manly pair of baggy jeans while on a family trip to Disneyland.

Posh looked like she'd raided her husband's wardrobe, teaming the loose-fitting denim with a cleavage-covering black t-shirt.

Walking tall: Posh's usual attire

And for once, practicality overruled fashion in the footwear department, with Posh resigning herself to a pair of flip flops instead of her signature six-inch heels.

The jeans proved a particularly unusual choice, considering Posh has spent months promoting her own dVb brand of slim-line denim both in the US and UK.

The range hasn't exactly been a hit Stateside - in April her jeans were taken off the shelves of L.A's designer boutiques and dumped into the bins of bargain basement superstores.

And now it seems not even Posh is a fan of her own trademark look.

She was joined by her husband David and sons Brooklyn, nine, Romeo, seven, and Cruz, three, but six hours in the Californian sun was too much for the littlest Beckham, who was soon fast asleep.

Meanwhile, David has just been named one of the 10 most powerful celebrities in the world by Forbes magazine.

The LA Galaxy star, who earned £25 million in the past year, jumped from 15th to fifth place on this year's list, beating out other megawatt stars including Madonna, The Rolling Stones and Elton John.

Posh also makes an appearance on the list, coming in at 50 as part of the Spice Girls.

The couple's close friend, celebrity chef Gordon Ramsay, made the list for the first time in 95th place.

Chat show host Oprah Winfrey retained her position at the top spot of the list thanks to her ability to draw in 30 million viewers a week and  yearly earnings of £140 million.
