Mr. Big Gets Smaller: Chris Noth Loses Weight

55-year-old Chris Noth has clearly been putting in the hours at the gym. And to show off his handiwork, he left his shirt at home and hit the waves on the beach in Miami on vacation.

The star of Sex and the City revealed a decidedly more toned physique than we’ve seen on him in quite some time. Additionally, the actor appeared to be sporting a ring on his “wedding finger,” sparking rumors that he and fiancee, Tara Wilson, have already tied the knot.

If that’s the case, then married life certainly agrees with him. Being in love must burn calories and build muscle.
