Fans are certain that Camila Cabello shaded Sabrina Carpenter after reports of a love triangle with Shawn Mendes resurfaced this week.

The “Havana” singer posted a TikTok selfie video of herself lip-syncing the lyrics to her song, “June Gloom,” which fans believe Cabello composed about Carpenter’s supposed relationship with the former’s on-and-off-again boyfriend of five years.

“She’s cool, I heard / Won’t act surprised, I saw the pictures / We’re a house fire, for sure.” I hope it burns away, but it only gets bigger. If she is so wonderful, why are you on this side of town? If you like her so much, what are you here to find out?” she inquired.

Camila Cabello posted a TikTok video of her lip-syncing her song “June Gloom.”

Fans have previously theorized “June Gloom” is about Sabrina Carpenter and Shawn Mendes.

Cabello, 27, cryptically captioned the video on Monday, “hope it’ll burn out but it just gets bigger .”

The former Fifth Harmony member wore a black lace top. She also sported a glam makeup look while she kept her blond hair down and teased.

The video quickly spent fans into a tailspin as they left comments about the alleged “messy” love triangle.

Cabello quickly received thousands of comments talking about the alleged love triangle.

Some social media users also pointed out how her hair resembles Carpenter’s signature blond bangs.

“Posting this now is so messy,” one user wrote under the video.

“i cannot take my favs being in a love triangle again please can we just blame the man,” someone else pointed out.

“The song is messy . Her posting this is amazing,” another person raved.

“promoting this song with the blonde hair is a whole other level & im here for it,” someone else wrote.

“This is INSANE timing and honestly…. I support it fully. Like okay fine I’d do the same ,” another user added.

Many fans also pointed out the resemblance of the two women after Cabello went blond and got bangs –– like Carpenter’s signature look –– but Cabello has rocked the hairstyle since February.

Cabello posted the video after Carpenter, 25, released her new album, “Short n’ Sweet,” which features a few songs that fans think are about Mendes, 26.

Carpenter’s album starts with the song “Taste,” where she sings about a mystery man not being able to decide between his ex-girlfriend and someone new.

“I heard you’re back together and if that’s true / You’ll just have to taste me when he’s kissin’ you / If you want forever, I bet you do / Just know you’ll taste me too,” Carpenter sings.

The “Espresso” songstress also seemed to allude to the alleged love triangle in her song “Coincidence.”

“What a surprise, your phone just died / Your car drove itself from LA to her thighs / Palm Springs looks nice, but who’s by your side? Damn it, she looks kinda like the girl you outgrew / Least that’s what you said / What a coincidence,” she sings.

Fans theorized the song is about Mendes and Cabello, because they were seen packing on the PDA at Coachella –– which famously takes place in Palm Springs –– in April 2023. Mendes and Carpenter were seen hanging out just one month before the music festival.

Mendes and Cabello first confirmed their relationship with their steamy “Señorita” music video in 2019. They dated for two years before calling it quits in November 2021.

While they continued to be seen together periodically over the next few years, they didn’t officially get back together.

In the midst of their on-again, off-again relationship, Mendes sparked romance rumors with Carpenter when they were seen hanging out and leaving two A-list after-parties together in February and March 2023.

Mendes, who previously denied dating Carpenter, has yet to address the alleged love triangle.

Mendes said they were “not dating” but was caught making out and holding hands with Cabello just one month later.

Rumors of a love triangle rekindled this week when MTV revealed that Mendes, along with Cabello and Carpenter, would perform at the forthcoming 2024 Video Music Awards.

Meanwhile, Mendes hasn’t mentioned any of the supposed controversy in his social media posts.
