His rep has denied he's dating Made In Chelsea star Caggie Dunlop but it seems Harry Styles may have set his sights on someone more familiar - the heart-throb is said to be back in touch with ex-girlfriend Caroline Flack.
Harry and cougar Caroline split in January this year after a brief fling but it seems the One Direction warbler may be interested in reigniting the pair's former flame.
The boyband star was rewarded with some time off by music bosses after working hard to continue their success in America and Harry has been using his free time to text TV host Caroline.
A source told The Sun: "Harry has never quite got over what he had with Caroline. They had such fun together. He sent her a few texts just to test the water as a lot has happened since they were together - particularly Harry being linked to a series of girls. She's also a touch wary because of the abuse she got last time for dating him."
Speculation surrounding the pop hunk's love life mounted after he was seen looking close to Made In Chelsea reality star Caggie at a London nightspot last Thursday but his representative was quick to deny the pair was an item.
A spokesperson told the Sunday Mirror: "Harry and Caggie are not dating and are not romantically involved."
> IN PICS: CELEB AGE GAP RELATIONSHIPS
Brad Pitt and Angelina Jolie - 12 years
It's easy to forget that there's quite a big gap in age between Brad and Ange, probably because he looks so much younger than his 46 years
Madonna and Jesus Luz - 28 years
The 10-year age gap with Guy Richie obviously wasn't enough for Madge, because her next flame was just 23 years old - while she was aged 51. It seemed like a fling at first, but they lasted a fair old while before splitting up in early 2010
Mariah Carey and Nick Cannon - 10 years
There's a decade in age between Mariah Carey and her hubby Nick Cannon, she's 39 and he's 29 - but that's not much of a gap at all by modern celeb standards
Michael Douglas and Catherine Zeta Jones - 25 years
Quarter of a century is a fair old age gap in anybody's book, but Mickey and Cath seem happy enough together - and she was comfortable enough with the reputation that their marriage earned her to mock it in Intolerable Cruelty
Rod Stewart and Penny Lancaster - 26 years
For years Rod was known as the oldest swinger in town, but Penny has firmly tamed his roving ways and he seems devoted to her
Ronnie Wood and Ekaterina Ivanova - 42 years
But just to prove that age-gap relationships don't always work out well, Ronnie Wood famously left wife Jo for Ekaterina Ivanova - who is a whopping 42 years his junior. They've long-since broken up, which left Ekaterina free to enter the Celebrity Big Brother house and flirt with Basshunter
Sam Taylor-Wood and Aaron Johnson - 23 years
Sam and Aaron are more than 20 years apart, but they haven't let the hefty age gap stop them getting engaged and conceiving a child together
Stephen Fry and Steven Webb - 27 years
Stephen Fry had just split up with his partner of 14 years Daniel Cohen when he apparently began consoling himself in the arms of a much younger beau. His rumoured love interest was 25-year-old Steven Webb
Tom Cruise and Katie Holmes - 16 years
Plenty of people have been cynical about TomKat's marriage, but we're not goiong to cast any aspersions. Our lawyers wouldn't let us anyway, but they seem happy enough together
