This may be hard to believe, but on Monday, September 14, Logan Henderson turned 31 years old. The actor was only 19 when he starred in Big Time Rush, which means it has been over 10 years since the beloved Nickelodeon show premiered. Yep, the hilarious series aired its first episode on November 29, 2009 and concluded on July 25, 2013, and when it came to an end it was truly the end of an era.

In case you forgot, the show also starred Kendall Schmidt, Carlos PenaVegaJames Maslowand Ciara Bravo, and was about a group of high school friends who traded in their homework for the opportunity of a lifetime — to become a world famous boy band! The guys dropped some seriously epic bops together, embarked on five world tours and even got their own movie! Yeah, BTR was the boy band once upon a time, and the show forever holds a special place in our hearts.

Well guys, in honor of his birthday, we decided to do some investigating and see what she, the BTR members and the rest of the cast are up to now. And it turns out, a lot has changed for them. Some went on to release solo music of their own and star in a ton more movies and TV shows, while others started families of their own! They’ve all seriously come such a long way and accomplished so much over the last six years.
