David Beckham has confessed he was lost for words when his children asked him about the facts of life.
The 37-year-old footballer hunk took over H&M's Twitter feed for a live Q&A with fans to promote his new underwear collection, and was asked what was the funniest question his kids had ever asked him that he didn't know how to answer.
David said: "I think it would have to be the obvious one about the birds and the bees :)"
The pin-up has three sons, Brooklyn, 13, Romeo, 10 and Cruz, seven, and one-year-old daughter Harper with fashionista wife Victoria.
Things didn't all go smoothly for David's Twitter chat, however. He turned up late from training with new club Paris St Germain and was then bombarded with rude questions about his love life, which he ignored.
He revealed his favourite hairstyle was his "nice and easy" shaved head and his favourite tattoos were the ones he had for his children, adding, "No new ones planned yet, have to find some space".
David also revealed he is an aspiring artist and enjoys drawing cartoons, citing that as the career he would have chosen if he hadn't become a footballer.
He replied to Gary Lineker's question about becoming a football pundit when he retires, quipping, "If that's your job then yes, as you always seem to be on the beach". But he ruled out becoming a manager.
David unveiled his new underwear ad, directed by Guy Ritchie, which sees him stripped to his boxers, running around LA.
