Goodbye Justin Bieber, she is moving on -- Selena Gomez was seen enjoying a night out in the streets of London town with One Direction's Niall Horan over the weekend.

Jessy Barnett (JBarns), a fan of the celebrity pair, and her friend got close up with Gomez, 21, and Horan, 20, to take a snapshot with them, and shared it via Twitter on Sunday night. Also, she pasted a cat sticker to cover her face. "I'm the one with the cat face @selenagomez," the fan wrote the caption following.

The "Come and Get It" singer dated Justin Bieber on and off for a couple years. After their two-year relationship, she finally called it quits. Selena Gomez recently admitted that she finds it so hard to ignore the constant rumors and speculation that surrounds her private life, especially when it has to do with her former boyfriend.

"It does get to me," she said. "I'm a human and I feel those emotions of when people talk about you. It's never a good feeling 'cause half the time it's just bull, it's not real."

"In the real world I'll drive my car to the grocery store and buy myself some food. In the media world it's like, 'Oohhh, I drive my car to go somewhere secretive,'" she continued. "It gets too clouded so I just have good people around me. I'm very picky."

"The hardest part [is] just trying to find someone that will just love the core person and not anything else around it," Gomez added.
