The two met backstage last week when the band pre-recorded their song, "Story of my life".
Horan was further enchanted by Foster after she arranged for One Direction to meet an eight-year-old cancer patient, reports mirror.co.uk.
Since then he has been sending her messages asking for a date. And he's looking forward to seeing her again when the band performs at "The X Factor" finale after three weeks.
"Yes, Niall and I have been talking in private. He's the most famous person in my phone after Nicole Scherzinger. I hope he fancies me - he's cool," said Foster.
