Forbes.com have announced their annual list of 30 Under 30, featuring individuals with "amazing" achievements under the age of 30.
24-year-old Adele Adkins was chosen because her second album 21 has sold over 23 million copies worldwide, while Justin, 18, was picked because of his dedication to his career with the release of his third record and Believe world tour.
His fellow Canadian, Drake, also made the list, alongside Bruno, Lady Gaga, Taylor Swift, Katy Perry and Rihanna.
UK stars didn't fare too badly with Mumford And Sons' frontman Marcus Mumford, One Direction and Calvin Harris also on the top 30.
