The retired soccer star has paid tribute to his and Victoria Beckham's son Cruz on his eleventh birthday and praised his "amazing character".

Sharing a picture of his son on Instagram, he said: "Happy 11th birthday to our little man... 11 years of seeing him grow from a cheeky baby to a cheeky 11 year old...

"He makes us laugh every single day and has the most amazing character plus the biggest heart... Love you big boy (sic)"

As Cruz gets older, Victoria will no doubt be worrying about who he is dating as David previously revealed the 41-year-old fashion designer finds it difficult to watch her eldest son Brooklyn going out on dates.

He shared: "I think it's easier for me than Brooklyn's mum, you know? To see her little boy go out and date ... Obviously for mums I think it's slightly more difficult with the boys but obviously once Harper [their daughter] starts [dating] ... I don't even want to think about that at the moment."

David and Victoria - who tied the knot in 1999 - also have daughter Harper, four, and son Romeo, 13.
