An article in In Touch magazine alleges that Smart also visited an "exotic massage parlor" in the same building as the establishment mentioned in the Star story. The In Touch story says Smart denied, via his rep, that he visited the massage parlor. In a statement to ET, In Touch said, "we stand by our story."
