‘Millionaire Matchmaker’ Patti Stanger on Jennifer Aniston and Justin Theroux: ‘I Hope It Lasts’ (EXCLUSIVE VIDEO)

After years of heartbreak, failed relationships and divorce, Jennifer Aniston appears to have found love again with her current beau, fiance Justin Theroux.

But will their relationship actually last? Maybe, says relationship expert Patti Stanger.

“Tough question,” Stanger told Celebuzz on Thursday while promoting her new season of Millionaire Matchmaker. “He left a girlfriend [costume designer Heidi Bivens] after 14 years.”

“I think he’s got her roped in,” she continued. “I hope it lasts. I can’t say 100 percent, because I don’t like the way you get a guy is the way you lose a guy. It kind of reminded me of Julia Roberts back in the day, with Danny [Moder].”

“I hope it lasts. But I also hope his ex-girlfriend finds true love, and I’ll fix you up if he doesn’t.”

Though never confirmed, reports circulated last year that Theroux’s relationship with Aniston, whom he met on the set of Wanderlust, blossomed while he was still with Bivens.

Bivens confirmed she moved out of the home she shared with Theroux in July.

Aniston and Theroux got engaged on Fri., Aug. 10, at Blue Hill restaurant in Manhattan, after dating for more than a year.

Stanger, meanwhile, is surely celebrating the success of Millionaire Matchmaker: the show’s season premiere debuted Thursday to the tune of 1.4 million viewers. That makes it Stanger’s highest-rated season opening in the show’s history.
