Cause everything she releases slays.

That's all.

She has more money than Katy Perry and has sold double the amount of records, so I don't think she is jealous of anything.

She's jealous of the big balloons for sure.

The ****ing DELUSION.

Because she's stealing some of her ideas. The horse, and the paint interlude...it's quite obvious for anyone to be honest.

But I think she's jealous that Katy is having more success currently because I think Gaga knows she's more talented and deserves the same/more success as Katy has. Just my two cents.

Her beauty,success.

Not her boyfriends.

Any of gaga's boyfriends, any man would rather be with a woman like Katy tho.

Lol @ "talent"

Because Katy overshadowed her this era & she is salty AF about it.

Thriving career

Katy is currently more successful than Gaga (and will continue to be more successful as the quality of Gaga's music gets worse and worse although it seems humanly impossible that her music can get any crappier at this point but I'm sure she'll make it happen).

Not when Katy can't keep a man for more than 2 years. Must not be that much of a catch.
