“The City” star Whitney Port has a contingency plan no matter what happens with her MTV reality show, which is rumored to be facing cancellation after this season. Port is the spokeswoman for an acne-fighting treatment, Zeno, and will film a new campaign tomorrow for its latest product, the Zeno Heat Treat. The commercial will show Port stroking the stuff on her face while lounging poolside in a white bikini at a private estate in Nyack.
