Marg (pronounced Mar-guh) Helgenberger got red hot reviews as the stripper turned crime scene investigator on the CBS smash CSI. Probe into this stunning strawberry blonde's past and you'll find that she's been sizzling and showing skin onscreen for quite some time. Her big break came via the 1988 ABC series China Beach, where she scored an Emmy for Best Supporting Actress. (Who wouldn't fantasize about being stranded on a desert island with her character, the fiery prostitute K.C.?) Marg was in the breast company, with Traci Lords and Joanna Cassidy, on the ABC fright fest The Tommyknockers (1993). That threesome set a record for the most pairs of perfect knocks ever seen together in a TV mini-series. You'll be moved to breed after watching Marg's performances in Species (1995) and Species 2 (1998). She appeared in all her rosy-nipped glory alongside man-eater Natasha Henstridge. Helgenberger's most skinful appearance, in Frame by Frame (1996), will really float your boat. Marg is completely nude in the bathtub, and if you look closely you'll get a quick peak of her reddish muffage before she covers it up with her fingers. There is a skindalous rumor going around that Marg will have a flashback on CSI, highlighting choice moments from her pole-dancing past. Should this happen, Mr. Skin promises to give the episode a thorough investigation.
