The 2015 Nickelodeon Kids' Choice Awards are quickly approaching, and we can't wait to see our fave hotties hit the red – or should we say orange! – carpet this weekend.
From the guys of Big Time Rush to the stylish lads of One Direction and tons of Nickelodeon actors like Nathan Kress and Avan Jogia, tons of our favorite hot guys have been hitting the event's orange carpet for years, and they've totally changed up their styles each time. Justin Bieber and Austin Mahone have really grown up since their first times at the event!
