Was it the horrifying pictures of her fiancé recklessly driving with their baby son on his lap that ended the relationship?
“They’ve been living apart," an insider told Life & Style magazine , saying that their wedding is off.
"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."
As RadarOnline.com previously reported, Mazur was recently spotted driving on a Los Angeles street with their son Noah illegally perched in his lap in the driver’s seat.
The pair have two children together, Noah and older daughter, Anja, and have been engaged since 2008 but their last public appearance was strained for the couple.
On Tuesday night, the Victoria’s Secret supermodel and Jamie both attended— but didn’t exactly act like a loving couple.
“They arrived and left separately,” an eyewitness said about the Day by Day fashion show in LA on October14.
“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.
“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 afterparty at Wax Rabbit — Jamie was nowhere in sight.”
