Michelle Williams and Katie Holmes went on to illustrious nude careers after their time on Dawson's Creek, and now Mary-Margaret Humes (whom you may remember as Dawson's Mom) is following in their footsteps with a belated skintroduction to onscreen nudity.

57-year-old Mary-Margaret made her MILF-alicious nude debut last night on the HBO series Luck, where she and Patti Tippo (nude in the 1983 Charles Bronson flick 10 to Midnight) co-star as insurance agents caught up in a gambling scam.

This week the ladies lured a co-conspirator into a hotel room for a three-way, where Mary-Margaret and Patti gave us a great look at their Dawson's Peaks before (and while) beating the crap out of their unfortunate third. Speaking of beating, excuse us for a minute...
