Anne Hathaway has a reason to party.

The Dark Knight Rises actress, 29, celebrated her engagement to fiancé Adam Shulman on Saturday night.

The 125-person fete was held at Housing Works Bookstore Café in downtown Manhattan, according to an attendee. There were no celebrities at the soirée – only family and friends.

"We hit it off immediately," Hathaway has said of her man, who proposed in November, adding at a different time that she is, "very much in love with him."
