'Glee': Britney Spears Gleeks out, tweets from set

britney-glee-twitpic320.gifIt has begun! Britney Spears announced on Twitter earlier today (August 18) that she was about to shoot her first scene for her highly anticipated "Glee" cameo appearance.

"About to do my first shot of the day for Glee tweeties! Here we goooo!" she wrote.

She also shared a Twitpic in which she and an unknown semi-lookalike are rocking librarian glasses. We'll say this: Spears is looking happy, healthy, and there's no sign of a bad weave as far as we can tell.

We know that everyone is sick of stunt casting and guest stars taking screen time away from regulars, but word is that Britney's appearance on "Glee" will be very background - more of a "Where's Waldo" game than a Chenoweth-style guest role. We're thrilled that the episode focuses on Heather Morris' character, Brittany -- she's one of the best characters on TV today and deserves more spotlight.
