Justin Bieber pictured kissing his ex Selena Gomez

If you had any doubts whether Selena Gomez and Justin Bieber were on-again, then this picture of them kissing puts all uncertainty to rest. 

Just a few days after Selena and her boyfriend, fellow musician The Weeknd, called time on their relationship in October, the former Disney star was seen hanging with her ex-lover, Justin Bieber. 

Justin reportedly reached out to Selena after she publicly revealed last month that she had undergone a kidney transplant. 

The pair have been seen riding bikes together, and taking walks in the park, but they avoided holding hands or acting lovey dovey in public - until now.

Selena watched the 'Sorry' singer play an amateur game of hockey in Los Angeles on Wednesday, and couldn't help planting a kiss on his lips. 

Justin and Selena have had a rocky relationship in the past, and have broken up on several occasions. 

They famously had a feud on Instagram in 2016 after Justin posted a picture of his then girlfriend, Sofia Richie - the daughter of Lionel Richie.

Bieber's fans did not like the relationship, and left nasty comments about Sofia on his page. 

He had enough of the hate, and warned his millions of followers that he would delete his Instagram account if they did not stop.

"I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand, if you guys are really fans you wouldn't be so mean to people that I like," he wrote.

Selena added her two cents worth, and threw some major shade at her ex in the comments section. 

"'If you can’t handle the hate then stop posting pictures of your girlfriend lol - it should be special between you two only. Don’t be mad at your fans. They love you," she commented.

Justin eventually did delete his Instagram account, and Selena apologised for her "selfish and pointless" comments.

Fans speculated that Selena, whose hit single 'The Heat Wants What It Wants' is reportedly about Justin, was not really over the Biebs.

And it seems they were right, because the on-again, off-again couple is giving love a chance one more time. 

Fans have been on 'Jelena' watch for weeks. This Twitter user says her cousin spotted the couple taking a romantic stroll in LA, and had a picture to prove it.

Now that 'Jelena' is officially back on, their fans have mixed feelings about the reunion.
