This just might be hollywood’s most expensive romance. ‘New Year’s Eve’ is the big buzz and the amount of celebrities in the film is quite a handful. Robert De Niro, Jon Bon Jovi, Zac Efron, Ashton Kutcher, Hilary Swank, Katherine Heigl, Sarah Jessica Parker, Josh Duhamel, Sofia Vergara, Michelle Pfeiffer, Lea Michele and Ryan Seacrest are just a few stars in the film. Heigl said it perfectly: “There are more celebrities here than rehab.” Who knows, maybe this movie might beat out ‘Valentines Day.’ Antsy to see who else is featured in the film? IMDb has the full list.
