What happened to the abdomen of Mark Wahlberg?

Remember those beautiful muscles turned and made famous by Mark Wahlberg as a Calvin Klein model?, Very sad today because I come to say that they are gone!, If, as I read a few days ago was captured by the lens a photographer with an unenviable set.

I do not know if it's a transformation for a movie, because in fact the photos were taken on the set of filming The Fighter, and really hope it is not that it has been abandoned to such a degree that he did lose appeal .

After the jump you can see more pictures of Mark with his new figure:
