Are Michelle Williams and Spike Jonze dating again?

After Spike Jonze invites Michelle Williams to an LCD Soundsystem show, is it safe to say this ex-couple is dating?

Michelle Williams' Blue Valentine may be blushing rose pink again, but Spike Jonze should be wary -- he may well encounter a few thorns. The Daily Mail reports that after a year and a half of being sent to his room without his supper, the Where the Wild Things Areand Being John Malkovich director invited Williams to see the band LCD Soundsystem in New York earlier this month.

Neither Williams nor Jonze has confirmed the rekindled romance, but the Daily Mail's source says Jonze realizes he made a poor decision in breaking up with Williams and wants her back. Williams, however, is not quite ready to jump into troubled waters again (their previous love match was her first serious relationship since Heath Ledger's death).

"He's promised that he's a changed man who is ready for a commitment," the source says, "but Michelle has told him to prove himself before she can trust him again."

Williams may be wise to wait; she also has the emotions of her daughter, five-year-old Matilda, to consider.

It remains to be seen if there is a future for Michelle Williams and Spike Jonze, and if the director will once again find his supper waiting for him, still hot.
