I think Britney should do the Vegas deal. It'll allow her to be there with her kids year round. And she'll get that practice for 8th era promo performances not to mention that 100m+ check I'm just worried she won't sell/people won't be interested because she isn't really someone the older people want to go see.
I don't get why some stans are crying over the Vegas deal. She is fully capable of releasing albums/singles and doing the Vegas shows at the same time.
