This week in Hollywood hookups

• Amy Adams is prepared to live happily ever after. The Enchanted star is engaged to actor Darren Legallo, whom she met in 2001; the Associated Press says the couple will marry next year. That’s how he knows that she loves him.

• Director Spike Jonze might be dating Heath Ledger’s ex, Michelle Williams, according to Star magazine. A witness tells the mag Williams and Jonze were smooching and caressing outside Spike’s New York apartment. Good news for the director, whose adaptation of Where the Wild Things Are isn’t going so well these days — its release date, originally slated for late this year, has been postponed until he and the studio can agree on a vision.

• This may necessitate a SPOILER ALERT! ... but according to People, a pair of castmates from this season of Project Runway are dating. The just-offed Wesley Nault says he’s in a relationship with Daniel Feld. “We met on the show,” he said. “And we tried to keep it very professional on the show because we were both there for our careers, and we didn’t expect this to come out of it. But I’m really happy.” Here's a photo of the happy couple from Bravo's Web site:
