What are some epic collaborations that'll never happen?

I'll start. If Beyonce and Chris Brown had ever collabo'd, the dance video and ensuing award show performances (minus any lipsynching) would have been epic. Oh well, never gonna happen.

Britney & Janet.

Britney & Kylie Minogue
September & Wynter Gordon
...

Michael Jackson & Whitney

Eminem and Gaga.

It could happen, but I'm pretty sure they hate each other.

Kanye and Gaga

One supports gay rights while the other....

madonna and gaga ft nicki minaj & lil kim

Oh my gosh, that would have been so amazing.

Beyonce & Rihanna
Ciara & Janet
Chris Brown & Usher
Britney & Christina
Britney & Gaga
J Cole & Andre 3000

It has already happend!!!

Song was called Alone Again. Madonna provided the song to Kylie. Kylie sung leads while Madonna did background. A Sample can be heard during Kylie's Doco "White Diamonds"

You got some good ones in there.

I doubt GaGa hates Eminem considering she went to his show in Detroit

Michael and Whitney were supposed to do "I Just Can't Stop Loving You" but Clive Davis said no because he didn't want Whitney to be "overexposed" dumbass

She would be against some of his so called views. The backlask in the gay community alone

What a terrible decision.

Rihanna & Bob Marley.

He changed his views on gays though

Aaliyah & Janet Jackson (they were actually planning on working together)
Michael & Chris Brown (idk y but I would want to hear it)
Left Eye & Nicki Minaj
Maxwell & Janet Jackson/Mariah Carey

yea lol
