Now that the Jonas Brothers are getting older, they're not spending quite as much time together as they used to. Kevin's a married man, Nick is busy working on a gazillion side projects, and Joe is constantly running around with his newest love, Ashley Greene. Seriously, I think they're joined at the hip. One week they're in Abu Dhabi getting stopped by airport security -- Joe, an avid cook, packed a cheese-cutting knife set in his carry-on luggage (oops!) -- the next they're adopting an adorable Bulldog puppy named Winston. Sounds like things are getting serious!
To top things off, the 21-year-old heartthrob was snapped toting an artificial Christmas tree into his gal pal's apartment on Monday afternoon. While it's every dutiful boyfriend's job to help with the heavy lifting, Joe seems to be in domestic bliss. Could the "Camp Rock 2" star be the next JoBro to walk down the aisle?
