Victoria Beckham
"You are our everything," the former Spice Girls star wrote in another, decidedly less sultry, post.
David marked the big day with a sweet throwback post on his Instagram page.
Victoria said it was “so special” to share in the couple’s celebrations, as she posted a picture on Instagram.
Someone get the BBC on the phone ASAP.
The former England captain also thanked Victoria for "inspiring" their children and keeping them "grounded".
The former Spice Girl's daughter-in-law Nicola Peltz was also in attendance at the Paris Fashion Week show.
The service was also attended by celebrities including Paloma Faith, Helena Bonham-Carter, Nick Cave and Jonathan Ross.
The couple threw it back to the height of their "Posh and Becks" era to celebrate Valentine's Day.
