What is Jennifer Aniston doing?

ok call me crazy, I know a lot of you guys out there will (and this question is for everybody), but here goes, does Jennifer Aniston seem like she's getting a little desperate for attention by posing naked on the cover of (i think it was GQ) that magazine, it just doesn't really seem like her, the funny girl, now she's daring and provocative? Jennifer Aniston? What is going on?
