Shawn Mendes and Camila Cabello continue to fuel dating rumors.

Over the weekend, the rumored couple was seen packing on the PDA during what appeared to be a date in Tampa, Florida—where Mendes performed in concert on Saturday (July 27). First, fans spotted the "Senorita" collaborators at a book store where the former Fifth Harmony singer could not keep her hands off the Canadian heartthrob.

Here's another video of them wandering around and talking to fans.

For those who still don't believe they're in a relationship, the two were also seen cuddling on a couch, having coffee together, and staring deeply into each other's eyes.

There's also this video of Mendes and Cabello kissing!

Earlier this month, E! News reported that Cabello has been following Mendes on his tour this summer because "neither of them wants to be away from each other," with sources saying, "She has the opportunity to be there with him and she's taking it."

Based on these new photos, it sure looks like the pair just can't get enough of each other. According to other insiders, their relationship is "moving quickly" because the timing is finally right for them. "They've known each other and been a part of each other's lives for a while so it's all very natural," the source explained.
