Now, that is being questioned since Selena and The Weeknd broke up... but let's look at how Sel and Justin reunited.
While it seems as though Sel has used her near-death experience to reconnect with old friends (she was spotted with fellow Disney star Demi Lovato for the first time in years on Tuesday night), I’m just going to put it out there: I don’t like this Bieber thing one. little. bit.
Sure, if their relationship was a) a thing of the past (given they had a public fight less than a year ago, I think not), or b) a healthy, loving relationship where a reconciliation would be a good thing (given Bieber cheated on Selena multiple times causing her to break down, I also think not).
Instead, I have a feeling this reunion is only going to end in heartache.
Let's quickly take a trip down memory lane, shall we?
Selena and Justin ended their on-off relationship in 2014, after around three years together. They first met in 2009, after their mums set them up on a date (yes, really), but the relationship wasn’t made official until 2011 when they attended Vanity Fair’s Oscar’s Party together.
It’s safe to say, the then-teenagers were each other’s first loves – official when Bieber was just 17 and Sel only 19.
“I moved in with my girlfriend when I was 18. Started my own life with her. It was a marriage kind of thing,” Bieber later told Complex. “We were so in love. Nothing else mattered,” he continued.
Their relationship was a classic teenage romance filled with breakups and posted-then-deleted social media blasts. They were each linked to other high-profile celebrities, with a slew of cheating rumours plaguing them (read: Bieber) for years.
Eventually, they called things off for good at the end of 2014, but things stayed messy throughout 2015 and until as recently as August of last year.
That’s right, in 2016 there were still feelings there.
First, Justin posted an old photo of him kissing Selena to Instagram, and to confuse things even further, she commented “perfect” on it.
Five months later, Bieber went public with then-girlfriend Sofia Richie and Selena had a very public rant on an Instagram photo of the pair, revealing for the first time that Bieber had cheated on her "multiple times".
She swiftly cancelled her world tour and checked herself into rehab, citing anxiety and depression as the reason, where she went without her phone for 90 days. Bieber reacted by deleting his Instagram account for six months.
Fast-forward to the present day and Selena was in a happy relationship with singer The Weeknd (Abel Tesfaye), her first public relationship since Bieber.
The Weeknd was reportedly well aware of his girlfriend spending time with her ex and was 'fine' with it, but honestly, we doubt that now.
It’s been just one year since Selena publicly acknowledged her feelings for Bieber – feelings that were so strong they contributed to her getting professional help for her mental health. Bieber has publicly said multiple times he will always love her – even once saying he wished he’d met her five years later in life.
Not to mention, mere months before he was spotted at Selena's house, Bieber released a song titled "Friends" with lyrics, "do you wonder why I've been callin'?" and "can we still be friends?". In that same song, which is almost definitely about Selena, Biebs sounds like he still has feelings for whoever it's about (read: Selena) when he sings "wonderin' if you think about me, actually, don't answer that."
It seems obvious these two will always have a “thing” for each other, and it seems even more obvious that Justin's motives aren’t purely to be friends with Selena.
In my humble opinion, he should back off and leave Selena alone – she seems happier and healthier than we’ve seen her in a long time, the last thing she needs is her cheating ex-boyfriend trying to drag her back down.
Biebs, haven’t you ever heard the saying "if you love someone, let them go"?
