In case you missed it, the lineup for this year's iHeart Radio Music Festival lineup is the BIGGEST and BEST YET. With so many great headliners in the mix, Ryan understandably had a hard time choosing which artist(s) he is most excited to see perform in Vegas.
He's really not kidding about The Weeknd, though. Protect your organs!!
