Selena Gomez and Niall Horan continued to inspire speculation over their relationship on Sunday when they were spotted leaving the same party.

Both stars, who have been fueling romance rumors since earlier this month, were photographed leaving One Direction‘s X Factor UK afterparty in London.

The band gave their last performance as a group on the reality competition show before taking an extended hiatus.

One Direction got their start on The X Factor UK, and sang two of their recent hits on the series’ season finale Sunday night, which was held at the city’s Wembley stadium. Over the summer, the group announced their decision to take a hiatus and will not record any new music together for at least a year.

Gomez – who last dated Justin Bieber on-and-off for several years – and Horan, 22, were reportedly spotted kissing at Jenna Dewan-Tatum’s star-studded birthday party in Los Angeles earlier this month.

A day later, the pair were seen by fans at the Santa Monica Pier in Los Angeles, riding a rollercoaster together and playing at game booths.

However, Gomez denied that the two were dating earlier this week.

“Oh my god! No,” the singer said when asked if she was dating Horan. However, she does say that the two are good friends.

“I love him, I always have. He’s amazing.”
