“Double date?” the newly-married pop star commented on a black-and-white snap of a smiling, shirtless Simpson following a recent swim race.
While Bieber tied the knot (again!) with wife Hailey Bieber in a lavish South Carolina ceremony on Sept. 30, the Australian singer has caused waves recently with his new relationship with Miley Cyrus. Most recently, the two shared a series of mirror selfies following Cyrus' return home from the hospital after undergoing surgery for tonsilitis.
Back in the day, Simpson served as one of the opening acts for Bieber’s 2012 Believe Tour.
