Photo Flash: MIRANDA SINGS at Birdland

On Monday, September 14, internet superstar Miranda Sings wowed the sold-out Broadway at Birdland crowd with a musical extravaganza packed with special guests. Opening with "I Know It's Today," cast members from Shrek, Marissa O'Donnell and Leah Greenhaus, brought the dazzling diva to the stage with style. Adam Kantor, from the former cast of Rent, helped Miranda show off her dramatic skills with a death scene in "Little all of Rain."

She coached Ariana (13) Grande and brother Frankie James (Mamma Mia!) Grande in an uncomfortable love scene, "As Long As You're Mine," from Wicked. Jason Maniscalco sang his ode to The Talented One, "Miranda Song." Then, sixteen kids from Billy Elliott stormed the stage and subjected themselves to public acting, dance and vocal critiques. There were a few bewildered looks and some hurt feelings, but show business is hard, folks, and these kids learned early that a real live professional coach doesn't always give positive feedback.
