After her most recent heartbreak (a broken engagement to SNL cast member Pete Davidson), the 25-year-old singer dropped a new single, "Thank U, Next," which quickly went on to become her first number one debut. And just last week, she released a record-breaking music video to go along with it. For most people, that might be enough to replace memories of an ex, but for Grande it wasn't even close.
