The boy band star has allegedly been seeing Amy since Christmas, but both parties are keen to keep things on the down low at this early stage.
But is it just friendship? Or something more?
A source told the Sun that although the pair definitely have a ‘soft spot’ for each other, they’ve never actually taken their friendship that extra step.
'They're private people and they don't want to highlight their celebrity friends where possible,' they added.
'They have never discussed getting together but they have a soft spot for one another.'
Amy Willerton found fame when she won Miss Universe Great Britain in 2013.
She went on to star in I’m A Celebrity, Get Me Out of Here just months later, where she was romantically linked with TOWIE's Joey Essex - although the pair later went on to insist that they were nothing more than 'just friends'.
Now it seems as if the 22-year-old has found a brand-new friend in One Direction's Niall - although she's been very careful about not being seen sneaking in and out of his house.
Could romance be on the cards for these two? We know we’re getting ahead of ourselves, but just imagine how incredibly cute their cheeky blonde babies would be?
