All of them have chances, never say never. But out of them, Gaga is definitely the least likely to do it!

Out of the list, absolutely Gaga

none. they all still have a chance of doing it again.

LOL 'loyal fanbase'

I voted gaga but i think its kind of unfair that you included Gaga in the OP with the other girls.

mess at katy having so many votes
she improves every tour

Madonna

Katy: she takes so long for make a big tour, and that tour had like 200 dates
LOL

You're late sis.
We have at least 1 more massive tour, and then she will do something else, more intimate. Until her last breath.

You know why? Because she is an ARTIST. She won't retire never, until her death

I'm gonna say Katy just because one tour is not enough to see how her touring power is really like. Everyone else on that list has had multiple huge tours.

Madonna

I have no idea who believes that Katy will never have the Top Female Tour ever again. It's truly beyond me.

If I had to guess, possibly...Gaga?

Omg at Taylor's tour poster she looked so sweet and innocent.
Katy's is horrible. OT: Gaga

Demand for Katy is high. Same goes for Taykor, Bey, and Madonna. So gaga

The first option
