Let's face it, if anyone is going to 'do a Robbie' and make a dramatic exit from One Direction like Mr. Williams did at the height of Take That's fame, then it'll be Harry Styles.
And could that happen sooner, rather than later? We wouldn't bet against it judging by a few of the tell-tale signs we've been getting a whiff of lately.
We're speculating of course, so those emergency fan helplines can probably wait (for now) but it's no secret that Harry's the cool one of the band, the one with the naughty twinkle in his eye, the one with the cool mates and the one who 'doesn't think' he's bisexual. Which sounds rather a lot like Robbie circa 1995.
Need more convincing? Let's look at the evidence...
His circle of 'cool' friends
Harry chooses to spend his downtime away from Niall, Louis, Zayn and Liam. Well, he's probably sick of the sight of them after living in their pockets 24/7, but in a sign that he's moving further away from his bandmates, Harry is very much a member of London's cool crowd of fashionistas, models and TV folk. Nick Grimshaw, Cara Delevingne, Kelly Osbourne, Henry Holland and Pixie Geldof all feature in his inner circle - and no, the other four definitely aren't invited.
Louis and Zayn's beef with Hazza's BFF Nick Grimshaw
Speaking of Nick Grimshaw, he might be bosom buddies with Harry but his bandmates Louis Tomlinson and Zayn Malik definitely won't be getting a Christmas card from the Radio 1 breakfast DJ this year after a Twitter spat erupted earlier this month. It all kicked off when Grimmy, whilst not naming names, suggested Louis was a 'complainy popstar' after he moaned that he couldn't leave his hotel room in Oz because of the paparazzi. Later on, Louis took to Twitter with this simple jibe, “@grimmers < @chrisdjmoyles” before Zayn Malik waded in, tweeting: “Don’t know why people always have to get brave? Mind your own business." Everyone knows, you don't slate your mate's mates. It's the law. Unless that person is no longer your mate, of course.
Harry was the star attraction on the front row at London Fashion Week earlier this year - with designers desperate to have him front and centre as they debuted their latest collections and even the coolest fashionistas were spotted trying to get a snap of the floppy haired heartthrob. So where were the rest of the 1D boys? We guess their invites got lost in the post.
Just look at the above video of the One Direction lads announcing 1D Day earlier this month. Does that look like a unified band to you? In fact Harry looks like he's already in mourning in his all-black ensemble (unlike the rest of the band). And whilst Niall, Zayn, Louis and Liam appeared to be excited at the prospect of having their every move transmitted around the globe for a whole 24 hours, Harry looked and sounded like he'd rather have his face tattooed.
Harry Styles: the thinking woman's sexually active manchild. Coo as he poses in a photoshoot sporting a tasteful pastel pullover and clutching a puppy! And then think "WTF?" when you open up your newspaper to see that young Harry appears to have had his tits scribbled on by a toddler.
