Back together? Selena Gomez and Justin Bieber enjoy a day out

She's only just split from The Weeknd, but Selena Gomez is doing nothing to dispel rumours of a romantic reconciliation with ex Justin Bieber.

Shortly before the singer's split from the Canadian star The Weeknd, she was spotted hanging out with Justin, who she dated on and off from 2011 to 2015.

And now that the relationship is confirmed to be well and truly over, it appears that she could be sparking up a romance with her former boyfriend once again.

On Wednesday the former Disney starlet, 25, and Justin, 23, were pictured enjoying a bike ride in Los Angeles.

The pair, who were both dressed casually, were all smiles as they rode their bikes before grabbing a coffee together.

Just days before their outing it was reported that Selena and The Weeknd had split over their conflicting schedules.

An insider told People magazine: "She and Abel have been going back and forth for a few months about their relationship.

"It’s been hard with him being on tour and her shooting in New York. That wasn’t easy on them."

They added: "It’s been hard for them to come to the realisation that this is the direction things were heading, but it’s been hard for months."

Before their bike ride, Justin and Selena had been spending an increasing amount of time together.

And over the weekend the singer was spotted leaving her house wearing the same hooded sweater he had on the day before.

According to reports, the on-off couple first reunited following Selena's kidney transplant over the summer.

“Selena is simply trying to make peace with Justin after her illness," an insider told Us Weekly last week.

While a source close to Selena also told the publication: “Justin and Selena recently started speaking. I don’t know when exactly but it’s because of the same church they go to.

"The community there is pretty tight knit and Justin and Selena have a lot of mutual friends who brought them back together. They realised it was time to grow past their history and move on.

"They’re grown up a lot in the past couple of years and are mature about the situation.”

They added that The Weeknd - who presumably was still with Selena last week - was totally cool with the brunette and Justin rekindling their friendship.

The on-off pair enjoyed a roller coaster relationship from 2011 until finally splitting two years ago.
