"They're still on friendly terms because of the kids and spend time together, but for now, they are separated and there will be no wedding," the source claimed.

The couple's most recent appearance was at the Day by Day fashion show in L.A. on Tuesday. They sat side-by-side at the event, but a source told Radar Online that the two looked cold. "They arrived and left separately. She showed up smiling with two friends and hung out in the VIP area about 30 minutes before the show started. Jamie arrived with a pal just before it began," the source said.

"They sat together to watch the show, but as soon as it ended, Jamie and his friend left while Alessandra hung around to talk to her friends. She then went to the after-party at Wax Rabbit," the source added. "Jamie was nowhere in sight."
