Friends said there was "instant chemistry" between them.

On ITV2's Xtra Factor, it was revealed that the singers have been direct messaging each other on Twitter. However, Foster said the Irish singer has just been giving her "constructive criticism." She hesitantly gave her response while blushing. Watch her interview in the video below.

Foster also kept a promise made to 8-year-old cancer patient Stacey Mowle and introduced her to the band, who she is a huge fan of.

"[Niall] and the rest of the band met Stacey and her face lit up when she saw them," Foster said. "She's a huge fan so it was a dream come true. I also watched the boys do a run-through of their songs and Niall and I started messing around in the corridor backstage."

The singer also said, "I spent most of my time with Niall. He's really fun and very immature... He asked for my number and we've been talking. Niall tweeted me when we first met but now we just direct message."

Horan reportedly broke up with singer Ellie Goulding, 26, in September after less than a month together. Foster split from her boyfriend Joshante Amihyia in October.
