“Sorry Not Sorry” is the lead single on Lovato’s upcoming album, “Tell Me You Love Me,” which will come out on Sept. 29. This will be Lovato’s sixth studio album.

The song also reached the top 10 in Australia, Hungary, Ireland, Latvia, New Zealand and the United Kingdom, as well as the top 20 in Canada, the Czech Republic, Malaysia, Norway, Portugal, Scotland and Slovakia.
