Michelle Williams will wed director Spike Jonze before the end of the year, celebrity insiders claim.

“They’re in love and absolutely thrilled with each other,” a source told Star. “They don’t see why they should wait much longer.”

Spike and Michelle met on the set of her latest project, Synecdoche, last October. In the months since their first meeting, the Where The Wild Things Are director –the former husband of Sofia Coppola — has not only won over Williams, but he’s a big hit with her young daughter Matilda as well.

“Spike loves being with Matilda,” the source added. “He’s teaching her to skateboard and to ride a bike. He never makes Michelle feel like taking care of her is a burden, because he truly thinks of them all as a family.”
