Niall Horan and Barbara Palvin have been rumored to be dating for over a month.

However, the mystery is finally solved as a friend of One Direction singer confirms that the couple is officially "boyfriend and girlfriend."

The "Best Song Ever" singer and Victoria's Secret model enjoyed their low-key date night together at a local pub in Hertfordshire earlier this week, and a One Direction fan who spotted them at the venue revealed on Twitter that a friend of Horan had told her that the pair is officially dating.

"Niall's friend, who was with him tonight, told me that Barbara & Niall are boyfriend & girlfriend," tweeted Tamsyn Louise Ash, who is believed to be an acquaintance of the Midnight Memories singer. She also posted up the images of herself, Horan and Palvin all posing for the camera together.

The Hungarian model has kept a secret about her romantic relationship with the boy-bander on social media so far. However, she did reveal on Twitter that she had jetted to U.K. with her sister to celebrate New Year. Meanwhile, Horan returned to England after spending Christmas with his family in his native Ireland.

"Super excited for tomorrow, first trip only with @RealAnitaPalvin ! London... ya ready for the PalvinSisters? #doubletrouble," Palvin tweeted.

After meeting for their first time earlier this year on one of One Direction's trips stateside, Niall Horan and Barbara Palvin were first romantically linked when they were seen together at a London movie theater to see The Hunger Games: Catching Fire.
