Big Time Rush was definitely one of the most beloved shows on Nickelodeon. With a dreamy boy band, catchy songs, and hilarious moments, how could you not love the popular show?

Despite going their own ways and working on their own projects, the cast has definitely stuck together and supported one another with their solo endeavors.

The entire cast has grown up quite a bit since the series first aired, and J-14 is breaking down what cast members like James Maslow, Kendall Schmidt, Logan Henderson, Katelyn Tarver, and more look like now. It's crazy to see how similar and different some of them look!
