Doting Daddy David Beckham posted the SWEETEST tribute to his little girl

She turns four this week, but we have a feeling that no matter how many birthdays little Harper Beckham celebrates, she'll always be Daddy's girl. Proud father David Beckham took to Instagram to share a sweet picture of himself and his little lady celebrating her big day in the garden, complete with party hats. The world's hottest dad captioned the image:

"Sweet dreams my little 4 year old... I think Harper Seven has had a fun packed day with her little friends... Good night little lady ❤️"

Earlier on, and obviously feeling sentimental, Beckham posted one of the first ever photographs of himself with little Harper, taken when she was just a newborn. If you'll excuse us, we've got something in our eye.

Possibly my favourite picture of Harper of all time... 4 beautiful years with the most amazing little girl... Happy birthday big girl... ❤️
