Meet “Glee’s” sexy new Dance teacher…Ms. Kate Hudson (PHOTOS)

One thing we can’t understand by looking at this photo of Kate Hudson playing Glee’s sexy new dance instructor is, how this woman gave birth to a second child just last July??

Sure, nannies help…as do expensive personal gourmet chefs…
But, one thing they can’t help with is — self discipline, which Kate seems to have plenty of, in addition to great genes.

Kate’s been dancing up a storm on screen, as of late. First on the big screen in Nine and now on the TV screen in Glee, which returns September 13th. 

Kate plays “Cassandra July,” a dance instructor at Rachel’s (Lea Michele) new school — New York Academy for Dramatic Arts. She is supposed to be mentoring Rachel, but don’t expect any female bonding — we hear Ms. July is a real B-word!

You can kinda sense that in this spicy photo of Kate clinging to her male dance partner, while flaunting her rockin’ post-baby bod in a leotard and fishnets.

Bingham, her one year old baby boy, was her first child with Muse rocker Matt Bellamy. Her other son, Ryder, with ex-husband Chris Robinson, was born in January 2004.
