It's a question that's been buzzing among the singers' fanbases ever since the "Never Be the Same" star posted an image on social media with her former music collaborator from what looked to be a behind-the-scenes songwriting session.
"Canadian fury + Latin sass," Cabello captioned the image on Instagram, which shows her, guitar in hand, and Mendes sitting backstage at Boston's TD Garden, where the artists performed Tuesday night (December 4) at KISS 108's Jingle Ball.
As soon as the image hit the web, Camilizers and the Mendes Army went nuts for the likelihood of another collab between the two musicians who, if you recall, once teamed up for their 2015 Song of Summer hit "I Know What You Did Last Summer."
"I LOVE U BOTH OMG!! CAMILA WE NEED HEAR IKWYDLS ONE MORE TIME!! PLEASE MAKE IT HAPPEN!!" one user wrote. "SO ARE WE REALLY GETTING IKWYDLS PART 2??" another added, along with a screenshot of Cabello hinting at a potential sequel for the track on Instagram.
The Canadian performer and former Fifth Harmony member ascended the charts with their smash jam in its initial release, reaching the top 20 on the Billboard Hot 100 and merited the pair double honors at the iHeartRadio Much Music Video Awards for Fan Fave Video and Best Pop Video in 2016.
In short, we'd TOTALLY be down for "IKWYDLS" Part 2!
