If only this were what “tennis whites” referred to 06 of 07 MARIO LOPEZ Courtesy FreshPair “Mysterious and magical.” That’s how the Extra host described Rated M, his line of boxers and briefs, which he launched in March and swears are so comfortable that you forget you have them on. 07 of 07 CRISTIANO RONALDO Courtesy Emporio Armani The 2010 commercial for Armani shows the soccer player walking around his hotel room searching for his lost shirt.
