We're cutting the (bikini) strings this week on DVD and Blu-Ray, with Natalie Portman briefly baring her rear porthole in No Strings Attached, Michelle Williams tugging on heartstrings with an emotional (and nude) performance in Blue Valentine, and Denise Richards searching for NSA sex in Cougars, Inc.

It's also a good week for skingoria fans on DVD and Blu-ray, with scream queen Tiffany Shepis totally nude (except for the blood, of course) in The Violent Kind, and South Korean stunner San-ha Oh making a gory nude debut in I Saw the Devil.

portman stringsAshton Kutcher and Natalie Portman are a pair of pals who decide to use one another to fulfill their biological urges by becoming "sex friends" in the romantic comedy No Strings Attached (2010). Luckily, Natalie's clothes don't stay attached either and we get to see Ms. Portman's rear porthole for the second time in her career after she gets nailed by Ashton. Naughty Natalie!

Cutting between the beginning and the end of their relationship indie drama Blue Valentine (2010) stars Ryan Gosling and Michelle Williams as Dean and Cindy, a couple who get married young while Cindy is pregnant by another man. As Dean gets drunker and lazier and Cindy gets more ambitious about her life, their relationship starts to crumble, but not before we see Michelle's mams in the shower. Blue Valentine won't leave you with blue balls!

A precocious college dropout starts an escort service for older women in Cougars, Inc. (2011) In need of tuition money, Sam (Kyle Gallner) recruits a group of foxy, bored older women led by Judy (Denise Richards) for paid “playdates” with his horny adolescent buddies. 42 minutes in, you’ll grow along with the cougar service with a mamtastic montage of nude recruits Rebecca Chaney, Maia Swift and Keyonna Patterson getting topless with their young clients. Watch out- these cougars bite!

For those who like their kicks rough and wild, there’s no better fix than The Violent Kind (2010). Before the end of this party, a sharply dressed gang of rockabilly psychopaths, a demon fetus, and maybe even the end of the world will be on the table in this brain-boiling bloodbath from The Butcher Brothers. Scream queen Tiffany Shepis bares everything as the diabolically hot Michelle, who is laid out on a coffee table, bloody, hysterical, and fully nude. The Violent Kind will give you a violent hard-on!

in the South Korean shocker I Saw the Devil (2010). San-ha Oh bares some bloody, plastic wrapped boobage early in the film when she’s handcuffed to a pole by a pervy psycho, and a second victim bares boobs just before she gets chopped to bits. It's not everyone's cup of ginseng tea, but if you like your skingoria with a little Far East flair, I Saw the Devil will make you strangle your sausage!
