This fight is actually pretty basic, but it took me forever to realize the problem with this fight. If you need help actually beating this evil witch, you may want to try another guide. This guide is primarily in regard to the bug that catches you in an infinite battle of dancefloor jumping.
I had tried it over ten times before I realized something was wrong. I kept getting stuck in Phase Two of the fight (according to
https://gamefaqs.gamespot.com/xboxone/290755-new-super-lucky..., it says "After a certain point, we'll be able to go in for another hit on Meowmalade"), where after a few jumps on the dance floor I should be able to move on to the next phase of the fight, but I counted 159 dance floor jumps when I finally decided to call it quits on this game (my brain was already mush from the rest of this crappy game). I was stuck in an infinite boss fight sequence of hopping dance floor tiles. But then I thought of the old Xbox trick of re-install. So I uninstalled the game (plus a reboot in between) and re-installed it, and I was able to clear this infinite dance floor sequence. After this process I barely recognized the dance floor trick because it was so quick. I got to the point mentioned in the gamefaqs site I mentioned above where Buzzkill and Golem arrive and I couldn't believe my eyes, maybe I fixed this jinx! And shortly after bouncing on top of a few Buzzkill and Golem, I was right! And I squashed that nasty Gaga (Madonna) impersonator. Either impersonator I was happy to kill. Ok, Gaga not so much. But Madonna is blasphemic

Hopefully you aren't having this problem, but if you're stuck in Lady Gaga infinity, try a full uninstall (then reboot) and re-install. Good luck!
