Eagle-eye Victoria Beckham fans were left in hysterics after spotting David seemingly naked in the mirror in a pic she shared of her gym workout.
The 49-year-old updated her 30.8 million followers on Instagram about her fitness progress as she stunned in tight black gym leggings and a fitted cropped tee, taking fans through her workout.
The mum-of-four looked incredible, but it appears the focus was taken away from her stunning figure as fans couldn't help but spot David, 47, in the background. The former Man United star was caught seemingly naked with his athletic body captured flexing in the shots.
But, as the Mirror reports, because his bottom half is blurred with only his bare torso in view, fans thought the former footballer was rocking his birthday suit.
Even the former spice girl got involved in the hilarious joke, as she pointed out her husband with a little arrow on her story alongside two laughing face emojis.
The news follows as we reported earlier on Monday that David paid tribute to Victoria today as she celebrated her 49th birthday as he 'gushed' over his wife.
The father-of-four shared a snap of the couple with his 'Victoria' tattoo on display.
He captioned the adorable pic: "Happy Birthday to the most amazing wife and mummy x someone who inspires us every single day we love you and you deserve to have the most perfect day happy Birthday @victoriabeckham @brooklynpeltzbeckham @romeobeckham @cruzbeckham #HarperSeven."
The pop star turned fashion designer is spending her birthday with her husband David, and their four children - Brooklyn, 24, Romeo, 20, Cruz, 18, and Harper, 11 - as well as daughter-in-law Nicola Peltz, 28.
Victoria shared snaps of her out for dinner with her close family where she could be seen blowing out the candles on her birthday cake.
Victoria's son Romeo, 20, also shared a loving post to his mum alongside a picture of the pair cuddled up together.
He wrote: "Happy birthday to the best mum out there love you so much."
