Maude Apatow isn’t the little girl from ‘Knocked Up’ anymore

Remember that cute little curly-haired girl from “Knocked Up”? She’s not so little anymore.

Last week, Maude Apatow stepped out on the Sundance red carpet to promote her new film “Other People” – and we were blown away by how grown up she looked.

Now 17, the oldest daughter of Judd Apatow and Leslie Mann is poised to become the next big thing in Hollywood – and we can’t wait to see where her career takes her next.

Scroll through the gallery to see how she’s grown up since “Knocked Up” came out nearly 10 years ago.
