What do Darius Rucker and Kermit the Frog Have in Common?

They are both going to be on American Idol!!!! This makes me so happy! Just announced this week the season Finale will be this upcoming Sunday and Monday and Darius Rucker will join Kermit the Frog, Nick Jonas, Bebe Rexha and more on the finale! I'm hoping Bebe will bring out Florida Georgia Line as well. I'm loving this  season of Idol so much! What do you think?!
