Kelly Clarkson will eventually go 2x platinum with Wrapped In Red 'cause it will keep selling every Christmas for a long time. Her other studio albums won't though imo.
BEYONCE will pass the 2 million mark next week I think. I don't think her following albums will do the same though.
Gaga...If she has a comeback, maybe she will. If not, nope.
Katy...I don't think so. But it's possible.
Pink, maybe. Why not? 4 out of her 7 albums are multi-platinum, including her latest one.
