Victoria Beckham has fruit fired at her by James Corden

She has become famous for her pouty and serious demeanour, even poking fun at herself recently by sporting a "Fashion Stole My Smile" T-shirt.

But Victoria Beckham let her hair down on The Late Show with James Corden as she took part in a gamer of Flinch. 

She - and fellow guests Lisa Kudrow and Jessica Chastain - took turns standing behind a clear partition as James fired fruit from a cannon at them and recorded their flinching.

James picked out a tomato for Victoria who went first and asked if she was nervous. 

"Totally. I'm scared of tomatoes," Victoria quipped.

She flinched hard as the cannon boomed and the tomato exploded on impact.

"That is not fun. And it's loud back there," Victoria said afterwards.

However, she seemed proud of her reaction times - posting a video of herself taking part in the game on her Instagram account alongside the caption: "Did I flinch? I didn't flinch?"

The former Spice Girl showed her cheeky side, when James took a turn behind the glass as she fired away quickly, catching James off guard. 

She hammered the point home on her social media account, writing: "Who knew fruit could be so scary?!? Got u @j_corden."

The singer-turned fashion designer looked preppy and smart in a black trouser suit for her appearance on the show where she was promoting her new capsule collection with U.S. store Target.

"I jumped at the chance to offer a line to women who don't want or can't afford designer prices," she said. 

The mother of four also said she was proud of her eldest child Brooklyn, 18, who is headed off to study photography in September at the Parsons School of Design in New York City

"Me and Brooklyn are very, very close. I'm so proud of him and everything that he's achieving. He wants to be a photographer," Victoria said.

The 42-year-old also took to Instagram to provide fans with a sneak peek at her performing Carpool Karaoke with James. 

Taking to Instagram, the 42-year-old delighted fans as she gave a backstage peek into the shoot in which she showed her hairdresser Ken Paves giving her a glamorous do before hopping in the Range Rover with her fellow Brit abroad.

Despite remaining quiet on the vocal front, the star, whose Spice Girls bandmates were Mel B, Mel C, Geri Halliwell and Emma Bunton, hint that she will be treating fans once more to her stellar singing on the American chat show.

On her Instagram story, Victoria, who was nicknamed Posh Spice, initially showed herself being primped and preened by Ken in which she claimed she was filming "a secret project".

She seemed to change her mind shortly after however as she shot scenes from within a car while saying: "So we are here about to film Carpool Karaoke."

The stunning star then turned her camera on her famous co-star as he climbed into the driving seat while she introduced him, saying: 'Here's James!'
