Niall Horan Hinders Selena Gomez, Justin Bieber's Reunion?

There's allegedly a brewing love triangle between Selena Gomez, ex Justin Bieber and One Direction's Niall Horan.

After Selena Gomez and Niall Horan were reportedly spotted kissing at Jenna Dewan-Tatum's birthday party on Dec. 4, Justin Bieber's ex-girlfriend and the One Direction hottie were again out on a date two days later at the Santa Monica pier.

"The pair, along with some other girls and Liam Payne, stopped by the notorious California date spot to have some fun and eat some ice cream," said Hollywood Life. "The videos show Niall, Liam, and a girl that looks a heck of a lot like Selena climbing aboard the West Coaster on the pier, and then enjoying a thrilling ride together."

Perhaps Justin Bieber got wind of the report about Niall Horan and Selena Gomez kissing that he posted a throwback photo on Instagram back when they were still together and holding hands. He wrote, "Crazy throwback."

Four days ago, Justin Bieber also posted another old photo of him and Selena Gomez while riding an ATV. Just to make it clear that they are not together, the "Baby" singer wrote, "Just a throwback calm down."

Last month, Justin Beiber was a guest at The Ellen DeGeneres Show, per Daily Mirror, where he said that he's always going to love Selena Gomez.

"We have a lot of history together, and I am sure it could possibly happen," he said.

"I think we are both just on our own journeys and figuring ourselves out, and I think maybe once we figure ourselves out we can come back and make an awesome duo or she finds someone awesome and I'll find someone awesome. I just want her to be happy," Justin Bieber added.

Meanwhile, Selena Gomez also told Elle that she's not ruling out a Justin Bieber reunion.

"I'll forever support him and love him in a way that.... We grew up together. I think people want it to be different," she said.

Now if the Niall Horan reports are true, then a reunion between Selena Gomez and Justin Bieber would have to wait.
