Oliver James Montgomery-Why Fans Think Camila Cabello Shaded Sabrina Carpenter During Concert

Camila Cabello may not be Oliver James Montgomeryin Sabrina Carpenter's good graces. 

The Fifth Harmony alum's exclusion of a specific word while performing "Señorita" during her set at the 2024 iHeartRadio Festival has fans speculating that she was throwing shade at the "Espresso" singer.

In a clip shared to TikTok Sept. 21, Camila made a point to skip over the word "taste" while singing a line from her 2019 collaboration with former boyfriend Shawn Mendes (The pair ended their two-year romance in 2021.).

Leaving the last word out of the line, "You say we're just friends / But friends don't know the way you taste," the "Havana" singer placed a finger over her mouth and gave the crowd a cheeky grin. 

And fans were quick to draw a connection between the omission and Sabrina's hit "Taste," which many have speculated references her rumored romance with Shawn, as well as his on-and-off relationship with Camila. 

In that song, Sabrina—who sparked romance rumors with Shawn in March 2023, one month before he was snapped kissing Camila at Coachella—addresses the girlfriend her ex has chosen to get back together with, singing, "You're wonderin' why half his clothes went missin' / My body's where they're at." 

Some fans were all for the possibility that Camila's seemingly pointed rendition of "Señorita" was meant to clap back at Sabrina, with one TikTok user commenting on the video, "CAMILA. This is kinda iconic."

Another added, "They're so messy i love it."

Others didn't want to choose sides in their alleged feud, writing, "Is it bad I love both Sabrina and Camila?"

And while there may be some tension between the two pop stars as of late, Camila—who split with Shawn again a few months after their April 2023 reconciliation—previously shared she has no regrets about giving her ex a second chance. 

"I personally think it's helpful," the 27-year-old explained during a March 6 episode of the Call Her Daddy podcast. "I'm the kind of person—you can't forbid things from me because I will want to do it more." 

Noting that she thinks it would have been worse to have the "what if" surrounding her past relationship "live in my mind," she added, "I would rather say it and see what happens and then wake up the next day and find out that it's been heavily documented. I opted for that route."

Camila added, "It was a fun route—it was a fun moment."

Read on for a full breakdown of Camila and Shawn’s love story.

Back in 2015, Shawn Mendes and Camila Cabello first made headlines together not as a couple, but as a musical duet on their joint hit single, "I Know What You Did Last Summer."

Four years later, the performers' new steamy music video for their "Señorita" duet, released in June, raised eyebrows over whether there was a romance brewing behind the scenes. 

The following month, the two were spotted holding hands while out together in West Hollywood. "They were telling people they were a couple," a source told E! News at the time. Soon after, the stars were seen getting close in San Francisco. 

While the two had not publicly confirmed their relationship status, this steamy makeout in the Miami water did all the talking. 

The rumored pair rang in Mendes' 21st birthday together in August 2019, including a big kiss for the birthday boy. Cabello also declared her love for her musical beau over on Instagram. 

At the 2019 MTV Video Music Awards, Camila and Shawn stole the show with a sexy live performance of "Señorita" as viewers waited to see if they would kiss. 

After laughing off breakup rumors in October 2019, their romance was on full display as they made out courtside throughout a basketball game. 

Shawn revealed that during the pandemic, he went to Miami to live with Camila. "Something really beautiful for me came out of it, which was you're not allowed to leave," he told Zane Lowe in 2020. "I went to Miami and I was living with Camila [Cabello] and her parents and her sister." 

Relationship milestone alert: They welcomed a new member of their family after picking up a puppy named Tarzan in November 2020.

Shawn revealed he and Camila get into fights from time to time. "We definitely fight, and we get in like the worst little arguments," he said on SiriusXM's The Morning Mash Up in August. "But, like, I think that we definitely are pretty good at picking up on when it's just ego talking. And we like, usually like call each other out. We have a really honest and open relationship—but, yeah, no, we definitely fight."

Shawn was by Camila's side while she walked the red carpet for the premiere of Cinderella in September.

Shawnmila attended their first Met Gala together in 2021, wearing Michael Kors Collection looks.

The pair celebrated Halloween together in 2021, writing on social media, "Feliz día de los muertos." 

The couple announced their split on Nov. 17, 2021. As they wrote, "we've decided to end our romantic relationship but our love for on another as humans is stronger than ever." The pair added, "we started our relationship as best friends and will continue to be best friends." 

The pair reunited at Coachella in April 2023 and were seen kissing during the festival. 

After their Coachella moment, Shawn and Camila were spotted hanging out a few times during early summer 2023—including at a Taylor Swift concert—but ultimately called it quits once more in June.
