What Happened To RiRi's Curves!?

Uh oh, looks like Rihanna is the latest celebrity to get slimmed down by photoshop!
The singer is on the cover of the newest issue of Elle‘s magazine and it’s raising some questions on whether or not the mag’s retoucher went overboard with the photo.
Some argue that even though she’s awkwardly posed at an angle RiRi’s head and waist measure out to about the same size, which is physically impossible.
Check out these un-‘shopped pictures of Rihanna’s figure at one of her concerts and compare it to the cover.
What do U think???
