More Heartbreak! Justin Theroux's Scorned Ex Heidi Bivens Blindsided By Jennifer Aniston Wedding News

Jennifer Aniston and Justin Theroux dated for more than four years before tying the knot Wednesday night in a surprise celebration. But before their big day, Theroux dated NYC stylist Heidi Bivens for a whopping 14 years -- only to dump her for Aniston. And the wedding news blindsided her yet again.

Reached by RadarOnline.com about her ex's wedding on Thursday morning, a stunned Bivens said she was "surprised" and declined to offer her congratulations before hanging up the phone.

Bivens was reportedly dumped by Theroux in March 2011, several months after he began filming Wanderlust with Aniston. The new couple were spotted out together beginning in May, and Bivens moved out of the apartment she had shared with Theroux in June.

By fall, Aniston reportedly held a secret meeting with Bivens in a suite at The Mercer hotel to clear the air about what actually happened between the three of them and get Bivens' blessing.

At the time, her mom Marilyn Bivens told Star, "It's a very complicated time for all of us."

When reached by RadarOnline.com about the wedding, she declined to comment.
