Jason Aldean is teasing his fans with a new duet called "If I Didn't Love You." He will not reveal who his co-singer is on the track. Fans have been taking some guesses, with many thinking that it could be his wife, Brittany. Jason's brother-in-law, Chuck Wicks, added to the mystery by commenting on the post, saying, "I know...I know...I know...Y'all gonna be FLOORED!!!" We'll find out who the secret singer is on Friday when Jason releases the single.
