UP's "Bringing Up Bates" series will mark 50 episodes tomorrow night.

In this new episode, "Birthdays and Boyfriends," the Bates are back in Florida and are ready to party! It's the Bates girls' turn this time to celebrate as Allie Jane and Carlin share a big birthday. The family prepares for the birthday bash, but quickly realize it's a lot harder to plan a party for both a 1-year-old and an 18-year-old than they originally thought. Then, Kelly Jo and Gil take advantage of their time in Florida when they decide to meet Tori's boyfriend's family.
