The two have been hanging out all the time, taking adorable photos together... and now, they've taken it to the next level.
Jacob just dropped his music video for new single "Chapstick," and the vid shows Jacob and Jenna exploring NYC together, from riding the subway to taking selfies in the park.
And at the end of the vid, they NEARLY KISS? Maybe they kissed off camera? Who knows...
Before the rumours began, Jacob tweeted that he had a "crush" and when asked about Jenna in particular on a live Q&A, he said he couldn't say who the girl was... but he loved Disney Channel's Stuck In The Middle... Jenna's TV show.
Watch his adorable music video below!
