I'd like her to collaborate with Ke$ha.
I don't know why,but Avril likes her music!

I don't know,I like the idea of a duet between Avril and Green Day.Why they hate her??Don't get that.Anyway,I think it would work out with Pink,maybe Paramore too...

Ashlee Simpson or Ke$ha

why not with Hayley Williams from Paramore

I'd like to hear her sing Canvas Bags with Tim Minchin

I would like her to collaborate with Amy lee, From Evanescence (:

I think P!nk would be good

I can imagine avril doing a duet with taylor swift, it would be perfect and beautiful.

Maybe Avril and Cassadee Pope, frontwoman of Hey Monday??

sometimes i want hear she rap,so maybe eminem.

P!nk or Eminem

And why not Blink 182?

With Avril, "All The Small Things" Live it gives this:

Taylor Swift

I would personally preferred if Avril doesn't collaborate with anyone. Avril is simply the best on her own and nobody can be anywhere near as good as her.

I really don't know why most people want her to collaborate with Ke$ha, she is just a "Wannabe Avril" but she will never be as good as Avril. Sure she writes her own songs like Avril does and has a couple of good songs, but we all know that Avril is 10X better.

You Rock Avril!

Or what about Kelly Clarkson?? Avril wrote her hit Breakway and they sing similar genre of music

How about Sam Brown, unbelievable voice, did the backing on lots of Pink Floyd stuff, most notably The Division Bell, both album and tour, but she also toured with them for their PULSE tour. She's also done backing vocals with Deep Purple and numerous other artists and groups, and teaches vocals somewhere in London, I think she's proven to some of the greatest musicians of all time that she has an astounding voice, so I'd quite like to hear that alongside Avril's almost, comparatively, gravelly voice.

Or for some reason, I've been trying to imagine what she'd sound like singing alongside Dave Gahan (Depeche Mode for those kids out there who aren't old enough to remember him dying for a few minutes and don't know such classics as Personal Jesus or Just Can't Get Enough!)

For the sheer sake of them getting together for ANYTHING at all, how about Avril and Pink Floyd. There's a gig I'd quite happily spend the rest of eternity reliving!

Everclear, Dada, Things of Stone and Wood, all GREAT bands with singers with decent voices that would compliment Avril's.

I know, it can be stupid, but I desire 'til 2002 that Avril did a duet with Green Day.
I know they all hate her, but both are punk, both are very great artists, so... why not?

I have another idea, Ke$ha

Sum 41...

Ke$ha

My list:

P!nk
Paramore
Green Day
Simple Plan
Eminem (not her rapping like maybe singing the chourus?)

In all honestly you have to find a strong voice for avril to do a duet with you can't just say Taylor Swift

Paramore or B.o.B, I love the song Airplanes so if Avril and B.o.B did something like that like Hayley and B.o.B did it would be cool

I don't like Paramore. I would like Avril to duet with East 17, Linkin Park, Pendulum, Kraftwerk or The Fray! I would also have said Scatman John but he's passed on.

I would love to see her do something with Orianthi. Avril could trade her vocal lessons for guitar lessons. I can't think of one decent guitar solo on anything Avril has ever released.
