Rapper Jermaine Dupri of So So Def has beef with Lil Nas X, we’re just not exactly sure why. We know that recently Lil Nas X’s “Old Town Road” broke the record of 16 weeks straight on top of the Billboard chart that was held Mariah Carey’s “One Sweet Day.” The Lil Nas X song now has owned the top slot for 18 straight weeks. On Wednesday, Dupri took to Twitter with a blast, “No!! You can’t sit with us. Go sit over there and based on the stats and this chart @mariahcarey is the greatest songwriter in history.” We’re not sure if Dupri just got done watching Mean Girls, if he was having a bad day or if he just wanted to show some love to Carey who he has collaborated with several times – most notably on “Always Be My Baby” back in ‘95. Meanwhile, in a show of graciousness, Mariah gave X a ton of props when he broke her record, so why is Dupri so salty?
