The former Spice Girl has been mocked in the past for scowling in public but poked fun of herself for sharing photos of her sons Romeo, 18 and Cruz, 16, wearing t-shirts with the words 'FFS SMILE' on Instagram.

Victoria joked "like mother like sons" in the caption and also shared a video montage of snaps of her grinning from her life.

In one picture from her childhood she flashes a smile as she poses in her Girl Guides uniform and another sees her smiling while holding Prince Harry's hand during her Spice Girls days.

Posh Spice once famously joked about her public image, saying: "I don't want to be seen smiling, having fun, or eating."

Victoria had previously revealed that she it was her husband David Beckham's smile that she "fell in love with first" when she met the former football star.

She gushed: "Let me tell you, love at first sight does exist.

"I fell in love with David's smile first, but as I got to know him, I just found such comfort in the way he made me feel… Like the best version of myself."

Victoria also admitted that she was "terribly" shy before finding fame with the Spice Girls during the 1990s.

The fashion designer explained: "Pre-Posh, I was just terribly shy.

"But my mum always encouraged me to use my voice to be kind and courageous.

"I learned then that your voice is powerful, no matter your age or notoriety."
