Miley Cyrus Practices Up For the Oscars

Tomorrow night, the Kodak Theater will be filled with all of Hollywood's biggest names. Meanwhile, on Saturday, celebrities strolled in one at a time.

According to AP reports, "The eve of the Academy Awards is rehearsal day for celebrity presenters. One by one, in 15-minute increments, Oscar winners and other famous folks come to the Kodak to walk on stage and practice their lines."

An insider tells: "A few academy officials brought their kids and grandkids to the theater Saturday, and just before 11 a.m., it became clear why: Miley Cyrus was coming in to rehearse. Accompanied by her look-alike mom, the gregarious teen star greeted her young fans — and everyone else she came across — with a megawatt grin."

Once the Hannah Montana star got through her lines, she "was coached by her mom and publicist - both urging her to slow down and to smile."

Also spotted going through her routine was Broadway star Kristin Chenoweth, who is set to perform "That's How You Know" from the movie "Enchanted" with singer Marlon Saunders.
