Victoria Beckham says she was told that her relationship with David Beckham 'wouldn't last'

• Victoria Beckham and David Beckham celebrated 23 years of marriage on July 4.

• The couple was initially told their union "wouldn't last." Now, they're married with four children.

Victoria Beckham celebrated her 23rd wedding anniversary with her husband David Beckham with a smiling photo of the couple on Instagram.

The former pop star and high-end fashion designer poked fun in her caption at the public perception that the pair often appear stony-faced while out in public. She also revealed that the couple had their fair share of naysayers at the beginning of their relationship.

"They say he isn't funny, they say I never smile, they said it wouldn't last Today we celebrate 23 years being married," she wrote in the caption.

"David you are my everything, I love you so much," she continued.

Victoria and David began dating in 1997 and their relationship immediately earned them the couple nickname of "Posh and Becks." Victoria told British Vogue it was "love at first sight" when they met in the Manchester United players' lounge. They were married in a lavish ceremony at Luttrellstown Castle in Ireland on July 4, 1999, and later renewed their vows in a private ceremony of only six attendees (though they did not share details about the event with the press).

The Beckhams have four children together: Romeo James, 19; Cruz David, 17; Harper Seven, 10; and Brooklyn Joseph, 23, who recently married actress Nicola Peltz.

David posted his own tribute to their union on his Instagram page. He shared a brief video of himself being asked by Sacha Baron Cohen (in character as Ali G) if he liked Victoria's pop music group the Spice Girls. The segment was part of an interview that took place 21 years ago during a comic relief segment on Red Nose Day (an annual fundraising campaign for child-centered charities).

"No," he replied quickly. "But I was into Posh."

"23 years ago today Posh became Mrs Beckham, but she will always be Posh," he wrote in the caption.

"Happy Anniversary WOW 23 years & 4 beautiful kiddies ❤️❤️❤️❤️ I love you, we all love you ❤️ @victoriabeckham."
