Why So Blue? Plus Filming Details!

Filming for High School Musical 3: Senior Year began on Saturday, as we all know. And we have some details for you! But before that, let's talk about Ashley Tisdale.

There are reports that Ashley has been down in the dumps lately. She had a police escort with her at all times and the only person she would talk to was Vanessa Hudgens. There's no word on why she's so sad, but we hope it doesn't affect her performance and that she cheers up soon! Plus, it's a good thing Vanessa was even there to hang out with Ashley - she wasn't even scheduled to shoot that day.

Now for some other notes on filming and such.

• Zac Efron, Chris Warren Jr., Ryne Sanborn, and Corbin Bleu have filmed some classroom scenes.
• Some of the last scenes have been shot (note: they don't shoot the scenes in order; "You Are the Music in Me (Sharpay Version)" was the last scene filmed in the second film).
• No outside scenes have been filmed yet.
• Ashley Tisdale has been seen wearing a pink cowgirl outfit (what scene will that be for?!?) and Olesya Rulin had been wearing sunglasses indoors all day. Apparently, the extras made fun of her.
• Director Kenny Ortega was put in charge of Ashley's dog.
• All actors have at least three security officers, a fan was escorted off the site, and several extras were asked to leave because of cell phone use.
