FYI -- in case anyone here is wondering (I went back a few pages and didn't see this tidbit, so I'm sharing because I wondered enough to go look) - - according to a post show interview, Blake said that he told Jordin that in the unlikely event that he won and had to sing that song, he wanted her to sing a duet with him.
I love my awesome crazy wonderful friends!!
