If you can believe it, G Hannelius turns 17 years old today! The actress has been a staple on the Disney Channel for years, and before she was on Dog With a Blog, she appeared in the Disney Channel Original Movie classic, Den Brother. (It's part of a long lineage of her playing Girl Scouts-esque characters. Just go with it.) The movie follows a big brother who becomes the "Den Brother" for his younger sister's Bumble Bee troop — and, obviously, hijinks ensue.

Do you love this movie? Can you believe everone has grown up so fast? Let us know in the comments!
