'There’s a local girl that Niall loves. I know he thinks of her as his sweetheart,' dad Bobby told heat magazine.
'She’s very attractive, and they’re close, but I don’t know whether he’s made any advances on her yet. I’m not going to embarrass her by giving her name, though.'
Of the mystery woman, he added, 'She would stand her ground with any of these beautiful celebrities. She’s a brunette with big brown eyes and pale skin like Niall’s. She’s from the town but the other end to us, and I always knew Niall has big feelings for her.'
But despite the teenager's hot celebrity status Bobby insists his son has never had an actual girlfriend.
He continued: 'He never really brought girls home. He had some girls that were friends and they would all sit on the wall outside together, but that was all.
'He’s never had a real girlfriend… He went to an all-boys’ school so it was hard to meet girls, but that’s certainly changed now.'
But that doesn't mean to say 51-year-old Bobby – who works as a butcher – doesn't think the More Than This singer has dabbled with relationships.
He adds, 'I don’t believe he’s a virgin. I couldn’t say, and I wasn’t in the house all the time, so I don’t really know what went on when I wasn’t there.'
