The cast of Big Time Rush just celebrated a Big Time Wedding this weekend! Katelyn Tarver married her guy David Blaise, and she shared her gorgeous day with tons of her Nickelodeon castmates. Not only did James Maslow, Carlos Pena, and Logan Henderson all suit up and reunite for the occasion, but there was even a too-cute-for-words Jendall moment when Kendall Schmidt hugged Kate on her big day.
We couldn't believe how different and grown-up the entire group looked! Everyone has gone through major style transformations since the show, and seeing Katelyn in a wedding gown is just unbelievable!
