The Singles Collection was something that not even her fans wanted... 3 was a hit, and that's all that matters.
Her next studio album will be successful, so... she's not a flop artist and you ALL know it.

omg... ME defending britney?

The video was funny as hell btw.

Well, maybe you should take a look at this then if you really think her career is dead:

LMFAO the Russian tragic song was my idea

lmao. I love it.

OK... so it is him. I was never sure.

I don't like seeing her [and Xtina] crying, though.

Too hard to find something with that voice funny.

didnt she expect that greatest hits usually doesnt sell

I done it. Still with the same opinion.

It is funny...

Anyway, Britney probably doesn't even know her last GH flopped, as mentioned above, not even the fans wanted it (I didn't buy a copy and I'm considering not to...) And why these haters care so much about this GH flop?

LOOOOOOOOOOOOOOL!

well it was expected funnt video!

It's really mean but too hilarious!

Madonna new greatest hits is over 1 million copies WW and she didnt promote it either
