The Jonas Brothers have secured their first ever Billboard Hot 100 number one record with their comeback single 'Sucker'.

The group - which includes brothers Nick Jonas, Kevin Jonas and Joe Jonas - topped the Billboard Hot 100 with their eagerly anticipated comeback single, making them the first group this century to debut at the coveted number one slot.

AHHH!!! This is unbelievable. My heart is so full of gratitude. There was a time I wasn’t sure if I was ever going to be able to make music with my brothers again, let alone have a number 1 song on the Hot 100 on Billboard. Thank you to every single person who downloaded, streamed and listened to #sucker on the radio. This still feels like a dream, and the best part is is that it’s just the beginning of this incredible new chapter. Thank you @philymack we truly do have the best manager and team in the business, and @republicrecords you guys are complete rockstars over there. Thank you for putting everything you had behind us. @ryantedder @louisbellmusic And @frankdukes Thank you for writing the perfect song for us to step back out with. All of our JONATICS! You guys are the best fans in the world, and we wouldn’t be anywhere without your endless love and support. This is gonna be an unforgettable ride. Get ready!
