Camila Cabello and Shawn Mendes would make an adorable pair, but the two pop singers are apparently just pals.

The two initially sparked up dating rumors after collaborating on Mendes' track, "I Know What You Did Last Summer," but when ET caught up with them at KIIS FM's iHeartRadio Jingle Ball in Los Angeles on Friday, both insisted that they're just close friends.

"We are just friends," Mendes told ET. "We're not dating."

"Yeah, we're just friends," Cabello confirmed. "He's like, one of my best friends. He's amazing."

During their individual interviews, however, the Fifth Harmony starlet and the Vine sensation couldn't stop flirting with each other from across the red carpet. "I'm trying to do an interview over here, OK?!" the 17-year-old Canadian crooner joked to Cabello, all while keeping a big smile on his face.

Cabello, 18, also addressed the breakup rumors surrounding her musical group, which is also made up of Ally Brooke, Lauren Jauregui, Dinah-Jane Hansen and Normani Hamilton.

"We're working on our second album right now," she told ET, noting that fans can expect to hear it in early 2016. "We are in the last few days recording. You're going to be hearing new music very soon, and that's that."

While the five girls are still powering through as a group -- Simon Cowell originally paired them together in 2012, during season two of The X-Factor -- Cabello knows that realistically, they won't be together forever.

"Obviously any band, any group, someday is not going to be together anymore," she explained. "That's the truth. [Everybody] kind of knows it, whether you say it or not. We're working on new music for you guys right now -- just be happy!"

ET also caught up with Pitch Perfect 2 actress Hailee Steinfeld at the Jingle Ball event, and she cleared up her own dating rumors, as she's recently been linked to singer Charlie Puth.
