Carey congratulated Lil Nas X for overtaking her hit, "One Sweet Day," as the longest-running number one song on the 'Billboard' Hot 100 chart. The viral cowboy rapper's mega-hit, "Old Town Road," has rolled into its 17th week at the top. Carey's 1995 duet with Boyz II Men spent 16 weeks at number one. The 20-year-old star replied immediately and hailed Mariah as a "legend and an icon" and admitted it was surreal getting a message from his idol.
