Holy hotness! Kate Hudson's new "Glee" character Cassandra July may be on par with Sue Sylvester (Jane Lynch) as worst teacher of the year, but who cares ... she smokin' hot!

toofab got an early peek at the first episode of "Glee" Season 4, where -- dare we say -- Kate steals the show with her "Americano"/"Dance Again" mash-up dance number. And this from a 33-year-old who just had a baby a year ago!

Watch Kate's full sexy performance of the Lady Gaga and Jennifer Lopez tunes above, and keep reading for some details about the premiere ep!

Rachel and New York Don't Get Along
Not only does Kate's Cassandra make life a living hell for Rachel (Lea Michele), but our prissy McKinley grad is also homesick, missing her (ex?) fiance Finn (Cory Monteith), and dealing with an apparently sex-crazed roommate. We're not in Lima, any more.

The New Kids are Amazing
We were worried about bringing in a slew of new cast members, but rest assured, they are all ridiculously talented (and good looking)! Even though we have yet to hear him sing, we have to say that Dean Geyer, who plays Rachel's potential new love interest at NYADA, could have us forgetting about Finn in a second!

Kurt's Gonna Be Ok
We were stunned when Kurt (Chris Colfer) wasn't accepted into NYADA with Rachel, but fear not, those besties find their way back to each other pretty quickly.

Winning a Show Choir Championship Can Go To Your Head
What happened to our humble New Directions? The first ep finds the returning singers as part of the "cool" kids now, with attitudes, assistants, and even making fun of someone at school who's different. How very UN-cool.

But with Rachel out of the picture, several are vying for the chance to be the new star of New Directions. Check out the battle as Blaine (Darren Criss), Tina (Jenna Ushkowitz), Brittany (Heather Morris) and Unique (Alex Newell) go head-to-head during Carly Rae Jepsen's "Call Me Maybe."
