Actress Emma Watson hosted a farewell dinner party at her home for her Harry Potter co-stars as the cast filmed their last scenes for the final movie in London.

The 20-year-old, who plays Hermione Granger in the wizard-fantasy series, invited the cast and crew to a dinner last week where they shared secret crushes and good memories, reports aceshowbiz.com.

"The last week of filming, Emma had a dinner at her place and we spoke about the best moments of filming.

Our secret crushes on set... all kinds of random questions. But all the answers to these questions will stay in that room," said actor James Phelps, who plays Fred Weasley in the movie.
