Shawn Mendes Would Pay $500 For Justin Bieber’s Underpants

Shawn Mendes has a lot to celebrate right about now. The 19-year-old is currently sitting at the top spot on the Billboard 200 with his self-titled, third album. Moving 182,000 equivalent album units, he is enjoying his largest opening week of all time and his third time atop the chart. Aside from being a personal best, it is also the second-largest week for a pop album in 2018 behind Justin Timberlake’s Man Of The Woods. The LP’s anthemic lead single, “In My Blood,” also soared up the Billboard Hot 100. Reaching a new peak at the number 11 spot, he is poised to enter the Top 10 with the right promotional push. And he is unlikely to suffer a second-week slump thanks in large part to a week-long residency on The Late Late Show With James Corden.
