A Vegas residency is a no brainer to me for Carrie! Lady Gaga, Bruno Mars, and many others have made Vegas cool again for A-listers. And the commitment can be however much or little the artist wants. This isn't an April Fools prank because it has been reported in the Las Vegas Review-Journal (a reputable newspaper) dating back to late 2019 that the president of this new resort/venue has been wanting Carrie for a residency. All the rumors for Katy Perry's residency at this venue ended up being true which makes me believe this one more. Also, the other day a Las Vegas realtor posted on Instagram a Carrie residency was coming then deleted her post when someone pointed out it hasn't been announced yet. So yes, this is all technically a rumor because noting has been announced, but it's not something just thrown out by a random Twitter account.
I'm a big fan of Vegas residency's and I'm hoping this is true because the residency exposes the artist to a new group of people and the setlist is not focused on one album - there is room for deep cuts and old singles! I don't see this as replacing a major tour for her next country album.
