The former “Bachelor” contestant, 27, surprised a class of sixth graders when he hopped on their Google Meet lesson Thursday to help teach a lesson about advertising on social media, Page Six has exclusively learned.

We hear a few female students were “freaking out” when the heartthrob came on-screen and the class was excited to have a famous TikToker online with them.

Cameron — who we’re told was “so funny” — spoke for 30 minutes about posting branded content as an influencer and how to social media in a positive way. He discussed dealing with internet trolls by not taking their mean comments to heart.

As the Post previously reported, New York City schools will remain closed for the rest of the school year due to the COVID-19 outbreak.

His rep did not immediately respond to our request for comment.
