Exactly. Gaga has yet to actually do Promo in the us. Once she does Born This Way will sell 3 million.

As for Rihanna and Beyonce. Beyonce is a force and she can sell as well. Rihanna is talentless and a flop. Proven time and time again by her floptasticular albums.

I rest my case.

P.S.
Shadey Grape Juice please don't post such misleading aritcle titles. For 21 to become one o the best selling albums of all time it needs to exceed 20 million sales worlwide. I'm sure it will get there, or very close enough. :)
