Anderson Cooper continues to let it be known, in every possible medium and format, that he is willing to entertain America's brave, well-toned troops in troubled hotspots should his services as a tough-but-emotionally-nurturing (and sometimes giggling) CNN anchor be required. You'll recall Cooper's message of support in Outside magazine's May issue: "I don't understand why more artists don't go and entertain the troops... I saw this documentary on Marlene Dietrich, and during World War II she was going out, right to the front lines. I think she was having sex with a lot of the troops, too." Cooper must have gotten to thinking about Dietrich's personal sacrifices, because a Rush & Molloy tipster just spotted him "looking patriotic in a USO tee on an early flight from New Orleans to JFK last week." Your salute to the troops, like those before it, will surely not go unnoticed, Anderson. [Daily News]
