Who's who?

So, I check out the MP3 Downloads page on Amazon.com and under the "New and Notable MP3s" heading, the following 2 CD covers appear right next to one another.... one for Adam Lambert and one for Rhianna.

Is it just me or do these 2 people look almost identical?! I'm sooo confused!

I don't pretend to know what's going on in the trendy hollywood popular world...but...well...yeah...
