Just read this on Digital Spy that Lady Gaga and Lily Allen are supporting each other, and although no indication that they actually would, a collaboration between them would be insanely good. I can imagine it being a hit.

I have also always thought that a Gaga & Madonna collab would be refreshing and settle a load of 'she's trying to copy her' comments on here. They could even make the song a reference to it.

Who do you think would be awesome in a collaboration together, and would have a hit?

Lana Del Rey and Lady GaGa

I definitely would love to see Madonna and Gaga collaborate!

Rihanna and Katy Perry.
Lana Del Rey and Lorde.
Britney and Gaga

And of course how has there never been Britney and Xtina.

Rhianna and Tarja Turunen

Eminem and Sharon Den Adel

Pet Shop Boys & Kate Bush

Collabs that I really want to hear are:
Little Mix & Pharell
Cher Lloyd & Justin Bieber
Christina Perri & Demi Lovato

I'd also like to hear maybe:
Cheryl Cole & Enrique
Emblem3 & Selena Gomez
Jessie J & Miley Cyrus
Lady Gaga & Adam Lambert
Rihanna & Kat Dahlia

Britney and Gaga
Britney and Xtina
Britney and Eminem

Actually I am surprised the Adam & Gaga collab hasn't happened yet. Jessie J & Cyrus would be either totally amazing. Or a complete disaster but interesting never the less.

Britney Spears and Janet Jackson

Pet Shop Boys and Madonna, properly this time not just them remixing a song for her.

natalia kills and madonna - so excited that this is actually happening!
robyn and royksopp - so excited that this is actually happening!

leona lewis and disclosure

Natalia Kills & Iggy Azalea
Lana Del Rey & Marina and The Diamonds
Ariana Grande & Angel Haze
Rihanna & Katy Perry
Beyoncé & Nicki Minaj
Neon Jungle & The Vamps

This, in my opinion, trumps everything.

This needs to be done but most importantly, it needs doing well.

im not sure a gaga madonna song would work - unless it wasn't commercial and more art based

the revolution of love project by madonna is against all prejudism and injustice

maybe a whole female pop collective: - gaga - madonna - miley - katy - beyonce - rihanna - britney - kylie

now that would be the dream!

They would need the assistance of fantastic producer(s), preferably dance-oriented. Somebody like Stuart Price, Disclosure, Madeon, Daft Punk or something more out-there, like Rustie, SBTRKT or Lone.

I'd settle for a track with catchy, intelligent, self-aware lyrics, some killer hook(s) and some fresh, infectious production myself!

Damon Albarn and Noel Gallagher.

Greg Dulli and Lana Del Rey.
The Tallest Man on Earth and First Aid Kit.
Katzenjammer and Gogol Bordello.

Nice.

Or Massive Attack and Kate Bush.

Kate Bush and Nikki Minaj

To the post above no way not ever Nicki Minaj stay away from Kate.

But what about Bowie, Bush that would be good .

I think Albarn/Gallagher might be happening, or at least they're open to it. How they soften with age.

My wish: Zayn Malik & Rihanna, produced by Naughty Boy or Pharrell.

My dream collaboration is Alison Krauss and my most favorite singer James Otto.

God bless you and them always!!!
