Justin Bieber-Selena Gomez Update: Bieber Seeks Answer From Niall Horan After Being Spotted Kissing Gomez, Report Says

Justin Bieber seeks answers from Niall Horan after the One Direction star was caught kissing Selena Gomez over the weekend, according to Hollywood Life. Bieber also had been recently posting throwback photos of former girlfriend Gomez.

According to Hollywood Life, a source said that Bieber was “hurt” over the dating rumors of his “friend” Horan and Gomez. The report added that the 21-year-old did not expect Gomez to date Horan.

“As far as Niall is concerned, Justin has been stung by the news,” the insider told the entertainment website. “He wants all the details of what went down. He is so hurt by this news and wants answers ASAP.”

It was reported recently that Horan and Gomez had PDA-packed Friday night at actress Jenna Dewan-Tatum’s 35th birthday party in Los Angeles. The two were reportedly seen “dancing close together all night, kissing on the lips and hugging a lot.”

Gomez and Horan were first spotted in public when they went out for dinner in November with their friends. The two have not yet publicly announced that they were dating and a source reportedly said they were “strictly friends.”

Bieber began dating Gomez in 2010 but the two broke up in 2012. Since then, the two singers have been in an on and off relationship. They were last seen together a couple last month when a photographer caught them at the Montage Beverly Hills Hotel.
