One Direction's Harry 'Dated 32-Year Old DJ Before Flack'
The 18-year old has been linked to Manchester Key 103's Lucy Horobin...
According to The Mirror, Styles - who was 17 at the time - was reportedly in a three-month romance with Lucy Horobin after meeting at her Key 103 show in Manchester, back in August 2011.
The tabloid claims that Horobin had been married for a year at the time of her fling with Harry, although they had allegedly been "living separate lives."
A source 'close' to Styles revealed: "Lucy was right up his street, exactly the type of girl, or woman, should I say, he is attracted to. She's sexy, confident and is doing well in her career. But he never wanted anything serious.
"She knows she shouldn't admit it but said the sex was amazing. He knew exactly what he was doing despite the fact he was only 17."
They continued: "He's adorable and Lucy had a lot of fun. But it was never anything serious. It was a mistake."
"She wanted to make a real go of her marriage and decided the only way to do that was to confess about Harry. She was terrified of admitting what she had done.
"Although she believes she was separated from her husband at the time, she knew he would hate it. But she knew it was the only way of moving forward."
The Sun has since uncovered footage of 1D's appearance on Lucy's radio show, and reports that Styles can be seen staring at Horobin as the group performed their No.1 hit, What Makes You Beautiful.
The 18-year old is then seen crossing his hands over his heart, mouthing the words: "I love you" at Lucy.
Horobin is yet to comment on the allegations, but has since taken to Twitter to post a 'sad face' smiley symbol - thought to be a reference to the revelations.
