Glee have gone and got us all excited by releasing a brilliant teaser promo for the upcoming fourth series. Or season, if you're American.

Now It may only be a 30 second clip, but don't despair - there's a whole lot packed in.

Not only do we see Kate Hudson playing Rachel's meanie-bum dance teacher in New York, but there's also a sneak peek at Sue Sylvester's baby!

Oh, one more thing before you watch the clip for yourselves: "That's a great haircut Mercedes, I thought you graduated?" - our favourite Brittany line EVER.

Glee Season 4 starts in September for our American readers... unfortunately the rest of us will have to make do with watching this promo over, and over, and over again for a little while longer.
