Lady Gaga and Bruno Mars finish the year with the top song on Billboard’s 2025 Hot 100. Their duet “Die With a Smile” led the chart for five weeks beginning in January, remained in the top 10 for 51 weeks, and spent a total of 60 weeks on the Hot 100, the longest run for either artist.⁠ ⁠ The single makes history as the first year-end No. 1 Hot 100 song performed by a male and female soloist in shared lead roles. It also expands both artists’ chart success, becoming Gaga’s sixth Hot 100 No. 1 and Mars’ ninth.⁠ ⁠ “Die With a Smile,” which they co-wrote and co-produced, joins a small group of hit duets that have defined a year and stands out as the signature song of 2025.⁠ #billboard #brunomars #ladygaga #diewithasmile #music
