Just last year, Isabelle Allen was playing the lead (as a boy) in a production of The Pied Piper of Hamelin at her school. Tonight, the 10-year-old actress will attend the star-studded premiere of her first big movie, Les Miserables.
ET's Christina McLarty caught up with the young thespian (who portrays the younger version of Amanda Seyfried's Cosette) at Dylan's Candy Bar in New York City, her first-ever visit to the Big Apple.
In preparation for the night's big premiere, Isabelle reveals she picked out a special dress for the occasion to make her feel like a princess.
"It's a white dress and it's got a netted skirt with little bits of sparkles in it and a bow," said the young actress proudly.
Co-stars Hugh Jackman, Anne Hathaway, Amanda Seyfried and Russell Crowe are expected to join Isabelle on the red carpet Monday, and as it turns out, the burgeoning star tells ET she forged great relationships with everyone on set.
