This dude really has got good reason to smile.

We spotted grinning Robert Pattinson as he left and after-party for the New Moon saga in NYC last night, and maybe the huge smile on his face was because he couldn’t stop thinking about the huge paycheck coming his way.

Rob, Kirsten Stewart and Taylor Lautner were all in attendance at the event.

And they too are laughing all the way to the bank due to the worldwide success of the Twilight phenomenon.
