^Christoper Walken in Madonna's "Bad Girl" is also a good cameo...

no Anna Kournikova?

Scarlett was amazing in "What Goes Around"


But what about Cassie in Kanye Wests "Stronger"? She looked fantastic in that video.

Robert Downy Jr is also great on "I Want Love" by Elton John

What about everyone in Johnny Cash's God's Gonna Cut You Down?

IKR? Way better than Hewitt.

I love the public affair cameo! So funny!

I wouldn't exactly call Christopher Walken's role in Weapon of Choice a cameo. Cameos are supposed to be brief and unexpected appearances.

What about NIckleback's Rockstar? There are so many cameos.

Yeah, cameos are brief appearances. Most of those aren't even cameos.

I was definately thinking of Alicia Silverstone and Liv Tyler, but I really feel that "A Public Affair" should be higher with all that star power.

LMAO i think i misunderstood the definition of Cameo, some of them almost appear more than the actual singer in the video. How is that a cameo?

Kate moss - The White Stripes - I Just Don't Know What To Do With Myself

Agree... But still, excellent #1!!!!!

haha, wut about Nickelback's "Rockstar" with Nelly Furtado and all those people?

Cassie in stronger was great!

and OMG Madonna at #5! Ali G was great there

**** this list. Milton Berle in the vid for Ratt's "Round and Round" ****ing rules, and I will not hear an argument.

And that's actually a cameo, unlike Walken in "Weapon of Choice", though I still adore that clip.
