Well, now we have an idea of what classic comedies may be on Justin Timberlake and Jessica Biel’s movie night rotation.

The stars hosted a John Hughes-themed Halloween party at their home Friday night, dressing in pig costumes as a reference to the ones the Griswolds wore in 1985’s National Lampoon’s European Vacation, a source tells PEOPLE.

The source adds that Timberlake, 33, was very doting and sweet to wife Biel, 32.

But the couple weren’t the only stars to cite ’80s movie references in their Halloween wear. Amy Adams dressed for the bash as Long Duk Dong from 1984’s Sixteen Candles.

Other stars attending included newly single Jennifer Lawrence, who partied without Chris Martin. The actress hit Timberlake and Biel’s affair with several girlfriends and was “having a great time,” adds another source.

Kate Bosworth and her husband Michael Polish, as well as Andy Samberg, rounded out the guest list.
