I often think of Robbie Williams when I think of Harry Styles. You just know that Harry will still be doing the 'whale' and running around in a sparkly jumpsuit with a tiara on when he is fifty-something, and getting out of breath after one too many attempted high kicks.
A little bit tubby and a little bit naff, but everyone goes "Awww Harry, do you remember when he used to be so cool", and all the younger generation will be like "What?! That fat embarrassing wanker. Eurgh, you lot seriously had dodgy taste".
Poor Robbie, he was such a hot cutie, it happens to us all....
When my daughter says "Do you think 1Direction will ever get back together?" I tell that it is a definite. Not if but when. Everyone gets back together when the fame starts to diminish and the price is right. Lets just hope they haven't gone too far into Dad Bod territory by then.
