It is rare to see the former Spice Girls member smiling in photos and whenever she is out in public. But on her latest Instagram video, Victoria Beckham shared her quirky side, as she walked gaudily around the Times Square, New York.

Her son Brooklyn Beckham took to his Instagram account and posted the video to promote his famous mom. He captioned it with, "My mum is bringing fashion to the streets. Times Square NYC."

According to Today, in the video, she showed off her sassy moves while dancing to the tune of Stayin' Alive by the pop music group, the Bee Gees.

Victoria Beckham was seen wearing loose white shirt and black trousers while strolling in the streets.

The 42 year-old mom did her fierce catwalk in the Big Apple's tourist attraction. When the crowd started to notice her, they joined dancing along with the fashion designer to the disco song.

The video lasted for 47 seconds and ended at the Brooklyn Diner, as she stood in front of the restaurant, which seemed as a praise to his son's name.

Stayin' Alive was popularized as one of the signature songs of the Bee Gees. It was a second single from the Saturday Night Fever soundtrack, as reported by Daily Mail.

Victoria Beckham is known as Posh Spice of British girl group the Spice Girls in the nineties. She married the football star David Beckham in 1999 and gave birth to three sons and a daughter.

Later on, she got into the world of fashion industry. Her designs are known to be simple with a keen use of colors.

Victoria created her own denim line in 2006 and also launched an eyewear collection on the same year.

She even introduced a fragrance line named Intimately Beckham.

It is no doubt that Victoria Beckham is more than just a fierce style icon, she also proved that she knows how to have fun and be a cool mom.
