Niall's secret? One Direction's Niall Horan has been spending some quality time with stunning Victoria's Secret model Barbara Palvin; both 20 years old, the Irish singer and Hungarian model were photographed together in London on Dec. 15, leaving the "X Factor" wrap party at the Marylbone One club. (The catwalker showed off her runway-ready legs in a black minidress and boots, paired with a black leather jacket; the "Best Song Ever" crooner wore jeans, a white t-shirt and maroon varsity jacket.)

The Daily Mail reports that the twosome met earlier this year in the U.S., and had a movie date last month, catching "The Hunger Games: Catching Fire" in London.

"He's getting to know her," a source close to Horan tells Us Weekly. "The guys have a few months off so they're having a good time before he goes back on tour. He plans on being home for the holidays. She's a nice girl!"

Although his bandmate Harry Styles' love life has made plenty of headlines, Horan's romantic profile has been more low-key -- although he's fessed up to a massive crush on a certain pop superstar. "Who doesn't have a crush on Katy Perry?" he asked recently.
