If you're trying to get the body of Leighton Meester or Blake Lively, you may not have to go to such extremes. In fact, all you have to do is go to your nearest department store and buy a pair of Spanx!
The TV show's costume designer Eric Damon spilled the beans on the starlet's beauty secrets saying:
"They don't [diet]. They just get some good underwear and they're fine. I say, just enjoy yourself. If you put on a couple of pounds, then great, buy some Spanx."
And there you have it.
Wonder if they make Ed Westwick wear one too?
