Wait – is Jelena potentially back on? One of the most enduring on / off celebrity relationships out there has possibly been reignited, after Justin Bieber fans claim they spotted Selena Gomez attending one of his live concerts.

Fans at the Biebs’ gig on Wednesday (March 23rd) at the Staples Center in Los Angeles flocked to social media to report that they had seen the Canadian star’s 23 year old ex-girlfriend in attendance.

The report comes just days after the ex-couple were said to have started texting each other again, after Bieber posted a cute throwback picture taken several years ago of them kissing.

22 year old Justin has stated that his new album Purpose, released at the back end of 2015 and a smash with the critics as well as his fanbase, was partially inspired by his former relationship and break-up with Selena.

Earlier this week, Bieber announced that he was cancelling all of his fan ‘meet and greet’ appointments indefinitely, claiming that he felt “drained and unhappy”, and amid rumours that he was speaking to Selena again, some thought it might be because he was pining for his ex.

All this is despite Gomez telling W magazine last month that she had finally washed her hands of Bieber once and for all. “I'm so exhausted,” she explained, “I honestly am so done. I care about his health and well-being. But I can't do it anymore.”

For his part, Bieber – who was until recently linked to Hailey Baldwin and had briefly dated Kourtney Kardashian at the end of 2015 – said he also didn’t have time for a relationship in his life.

“I don't want to put anyone in a position where they feel like I'm only theirs, only to be hurt in the end," he told GQ. “Right now in my life, I don't want to be held down by anything. I already have a lot that I have to commit to. A lot of responsibilities. I don't want to feel like the girl I love is an added responsibility. I know that in the past I've hurt people and said things that I didn't mean to make them happy in the moment.”
