But don't stress, it was just a joke!
While at the event, the radio hosts gave Camila some Christmas gifts, including a shirt that reads: "Mendes is my bae".
"It's a true statement," Camila said, immediately wanting to wear it in front of her boyfie.
"If the next time I saw him I wore this, it would be the funniest joke in the entire world," she said. "I just don’t know how he would react. He would literally be like 'who is this girl?'"
Shawn would never!
But hey... if you want your own version you can get it from Etsy below!
We know what we want for Christmas!
