Happy Birthday Rob Lowe and Kurt Russell!

Happy Birthday Rob Lowe and Kurt Russell!Though Kurt was rocking one of the hottest bodys in the business, he waited nine years to show his butt again, wowing us with his rump alongside Sylvester Stallone in the hit action flickTango Cash (1989). The sad thing is, unlike Lowe, Russell has yet to show any nudity since the 80s. Bummer.

Happy Birthday, guys!
