Anne Hathaway's fun engagement party

Anne Hathaway's engagement party was "so fun".

The 'Dark Knight Rises' actress and fiance Adam Schulman threw a party in a New York book store to celebrate their impending nuptials - which are expected to take place in October 2013 - last month and delighted guests with the quirky celebration.

Among the personal touches was a banquet of vegan food and decorations including bird-shaped vases filled with Anne's favourite flowers, ranunculus and anemones.

A source told Us Weekly magazine: "Everything so was fun, just like Annie."

Although pals revealed Anne and Adam have already selected a New York venue for their wedding, they are not planning to reveal where until the last minute.

A source said: "But they're keeping it a secret until right before!"

Anne and Adam - who started dating in 2008 following the actress' split from Raffaello Follieri after he pled guilty to 14 counts of money laundering, conspiracy and wire fraud - announced their engagement in November and Anne explained he "ruined" her plans to stay single.

She said: "We hit if off immediately but it took us a pretty long time to get together. He thought that I had a boyfriend and I thought that he had a girlfriend, so I thought that I'd better keep my distance because I didn't want to be that girl.

"I am very much in love with him, [only] Adam totally ruined my plan. I was really actually looking forward to a little alone time, and then I fell in love like a fool!"
