David Beckham shares sweet photos of daughter Harper to celebrate her 13th birthday

It's hard to believe that David and Victoria Beckham's youngest child Harper Seven is now a teenager, but to make the memorable occasion the power couple have taken to social media.

Doting dad David in particular posted an adorable video that captured him laughing with Harper when she was younger. As Michael Jackson's My Girl playing in the background, the footballer captioned the reel: "Every time daddy changed your nappy we would always dance to this song... OUR SONG FOREVER. Happy birthday to my princess."

And his wife of 25 years Victoria replied underneath: "U really are the best daddy x we love you so much xxx."

The 49 year old then included some throwback pictures on his Stories of Harper growing up, going from being a newborn to the 13 year old she is now.

Victoria also posted her own birthday tribute to Harper - who was born in 2011 - with the former Spice Girl calling her "our everything", reports the Mirror. The fashion icon referred to Harper as "my best friend", penning: "You are sweet and kind and your smile warms our hearts every day."

"You really are our everything Harper Seven and we are so proud of the happy, beautiful, talented young lady you are becoming. We love you so so much."

David - who also shares sons Brooklyn, 25, Romeo, 21, and Cruz, 19 with Victoria - then penned his own heartfelt message underneath, saying: "Happy 13th Birthday to my beautiful little girl."
