I Love katy perry! she's really talented! i wish that someday gaga and katy will do a duet! it would be so epic!

I don't like Katy Perry she's a really homophobic person, she insulted more than once to Lady Gaga, Tokio Hotel and my beautiful Bill Kaulitz, and I don't even allow my friends to do that, They are my favourite people in the world♥ (Lady Gaga and TH)...so no I don't like her, not even a bit ._.

she's in that movie but she cover her face

Trollga xD

This part and the divorce half of the film had me screaming and crying almost uncontrolably. Love them both. <3

i wanna see this movie

both katy and gaga are amazing

This was EDITIED, The oufit katy wore is what she wore at the ama's, gaga didnt attend the ama's she only attended ema's. I lost all my respect for katy, she just used us monsters to get higher rates.

It's not like gaga has a whole scene. It's only like 5 seconds

Katy did say Gaga looked like a hershey's kiss, which I felt was a bit insulting. I have nothing against her though.

JAJAJAJA so funny!!!

Ive never had a hate for kp like shes hella pretty super talented and just beautiful in general I went to 2 of her shows and loved each one idk why that people are hating on her shes so sweet!

Katy is a homophobe

she only put gaga in it, to increase the audience view, well but i don't hate katy!

I love Katy *---*

i used to listen to Katy's music, but i stopped when she tweeted that gaga is like a clown soo :| i just don't like her

This is not real gaga. Just a cameo appearance :) just for public knowledge to those who haven't watched the movie yet PAWS UP FOR THE KATTY CATS <3

i watched it! and i loved the movie! i've always loved katy! i liked katy the same year that i started liking gaga

is really she?

I loved Katy perry anyway! :D Shes fabulous
