"Little Miss Sunshine" is a big girl now!
Abigail Breslin showed up on the set of "New Year's Eve" yesterday in NYC -- looking completely different with long, blonde locks and a stylish orange peacoat as she walked alongside fashion icon Sarah Jessica Parker.
SJP reportedly plays the now-14-year-old's mother in the flick, which stars almost everyone in Hollywood -- including Halle Berry, Zac Efron, Sofia Vergara, Alyssa Milano, Katherine Heigl, Lea Michele, Jon Bon Jovi and many, many more.
