Camila Cabello and Shawn Mendes reunited for a lunch date this week.

A fan spotted the singers hanging out at a restaurant in Los Angeles on Monday (May 27), prompting the internet to speculate whether they're talking about their next collaboration. In the photo, the pair look like they're having a pretty serious conversation. It's unclear what this reunion means for them, but we can assume they're either going to collab on another song in the near future or the old pals simply met up to catch up on life.

Rumors of a collab have been swirling ever since the "Havana" hitmaker hinted at a possible musical reunion when she posted a photo with the Canadian pop star in December 2018. Though she didn't confirm anything, the image, which she captioned "Canadian fury + Latin sass," sure looks like they're cooking something up.

Regardless, fans believe something is going on between these two:

The last song Cabello and Mendes worked on together was "I Know What You Did Last Summer" in 2015. At the time, fans believed the two were dating and the rumors have followed them ever since. Though they always made it clear they're nothing more than just close friends, this hasn't stopped fans from shipping them as a couple.
