Character: Karen van der Beek
Season(s): 1-4
Why they were hot: As pretty much the only woman remotely capable of keeping Hank’s interest for more than five minutes, Karen is Hank’s ex-girlfriend and babymama to his teenage daugher, Becca. She’s outspoken, driven, independent, feisty, and she tends not to put up with Hank’s bullshit, which is pretty much the formula for a grade A hottie right there. Gotta love some feistiness.
