Finally, after much speculation, Shailene officially confirmed that she and Aaron are happily engaged during her virtual appearance on The Tonight Show Starring Jimmy Fallon. In fact, she told host Jimmy that they've actually "been engaged for a while now." She went on to say that she never saw herself marrying a football player, but after a "chat" with her dog, it was the end of the discussion. "When I first met him, my dog pulled me aside and was like, 'If you don't date this dude, I will disown you as my mother, because the three feet that I run with you when you throw a ball is nothing compared to the marathon I'm able to run with him,'" she recalled.
