The Beckhams headed to social media on April 17 to let you know how much they love their family matriarch.

Perhaps the sweetest birthday wishes came from Harper, Victoria and David Beckham's 5-year-old daughter. In a video posted to the former Spice Girl's Instagram page, the little one is recorded singing "Happy Birthday" to her mom while snapping along to the tune.

"🙏 I love u @davidbeckham @brooklynbeckham @romeobeckham @cruzbeckham 💕💕💕💕," Victoria captioned the way-too-adorable video.

David and Victoria's 12-year-old son Cruz also 632,000 followers to know how much he loved his "mum."

"Dear Mum happy birthday you are the best mum ever @victoriabeckham #bestmumever ❤️❤️😜," he wrote alongside a selfie of he and his mom.

David, too, couldn't pass up the opportunity to fawn over his wife, sharing a throwback photo from her Spice Girls days.

"Happy birthday to An amazing mummy , wife and friend .. We Love you Have a beautiful day," he said while also tagging their children.

Some of the family actually started celebrating Victoria's big day on April 16, dining at Nobu. Photographers captured David and Victoria as well as kids Romeo, Cruz and Harper at dinner in Malibu, Calif. (Brooklyn was at Coachella, so he missed the birthday festivities.)

Happy birthday, Posh Spice!
