Fans think Kourtney Kardashian has sided with Selena Gomez amid rumoured Hailey Bieber feud

There's a new player in the apparent 'feud' between Hailey Bieber and Selena Gomez: Kourtney Kardashian has entered the chat.

At this point I'm fairly certain those invested in the alleged beef between Hailey and Selena would find meaning in a bird flying past the window in the background of one of their videos, but even I have to admit, this one has legs.

Fans have pitted the two stars against one another for years since Hailey sparked up a relationship with Selena's ex, Justin Bieber, but the most recent instalment began earlier this year when fans became convinced Hailey was throwing shade at Selena in a since-deleted TikTok video.

Hailey insisted at the time it was 'not directed at anyone', while Selena encouraged people not to add fuel to the fire by writing "Be nice to everyone!" underneath a fan theory video.

Over the following weeks, speculation continued online with almost every new post or comment made by one of the two women, and recently Kylie Jenner got dragged in to the conversation.

Kylie's involvement came after Selena shared a video of her makeup, saying: “I accidentally laminated my eyebrows too much.”

A few hours later, Kylie posted a photo on her Instagram Story showing her own laminated eyebrows, alongside the caption: “This was an accident?”

When fans speculated she was mocking Selena, Kylie quickly tried to shut things down, writing: "This is reaching. No shade towards Selena ever, and I didn’t see her eyebrow posts! u guys are making something out of nothing. this is silly."

Fast forward to this week and another of the Kardashians has found themselves wrapped up in the alleged beef.

While many speculated Kylie's post was evidence of her taking sides with Hailey, Kourtney Kardashian was placed on Team Gomez after she used one of the singer's tracks in a TikTok video.

The video was posted by Kourtney's wellness brand, Lemme, and featured the track 'The Heart Wants What It Wants'.

This was all fans needed to start theorising, with one fan commenting: "Kourtney is team Selena."

"Oh Kourt!," began another, "You taking sides?! Amazing choice!"

A lot of fans have speculated that the use of the song is simply a good marketing technique - and I can't deny, it's got people talking.

Whatever the reason behind the song choice, though, Selena has made clear that she wants to move on from the rumours as she called out to her fans on Instagram last month, saying Hailey had been in touch to say she'd been receiving 'death threats and such hateful negativity'.

"This isn’t what I stand for. No one should have to experience hate or bullying. I’ve always advocated for kindness and really want this all to stop," Selena wrote.
