It could be on the of the biggest nights of her entire acting career, and Vanessa Hudgens is gearing up for the Los Angeles premiere of “High School Musical 3: Senior Year.”

The “Sneakernight” songstress was spotted by the paparazzi meandering around downtown LA earlier tonight, primping her hair and getting some fresh air before heading down to USC’s Gelen Center.

It’s a well-known fact that she had to gain weight for her role on “Desperate Housewives.” But last night (September 2), Eva Longoria was back to her sexy svelte shape, and she was all about showing it off.

The “Over Her Dead Body” babe sported a strapless silver dress as she cavorted around Los Angeles with friends, stopping off for dinner and then shopping at the Farmers Market at the Grove.

She's been busily promoting her soon-to-be-released movie "War, Inc.", but that doesn't mean that a Hilary Duff isn't willing to make time for a charity in need.

Following a Wednesday night appearance on the Tonight Show with Jay Leno (during which Adam Sandler announced that he and his wife and expecting their second child), Duff jetted off to Boca Raton with the motive of helping hungry children.
