Jennifer Aniston might be happily in love with a man she is about to marry, but it looks like she can't get over one of her exes. The Hollywood actress, who is reportedly set to marry Justin Theroux this summer, has supposedly hired a "confidence coach" as she's so scared of humiliating herself in case she runs into her ex-husband, Brad Pitt and his partner, Angelina Jolie.

Is Jennifer Aniston Jealous Of Her Brother's Pregnancy News?

According to reports, Aniston and Theroux have been invited to George Clooney's star-studded wedding in Italy in September, along with Pitt and Jolie. Aniston's publicist have worked overtime trying to keep her away from her ex-husband at Hollywood functions, but now it looks like she has no choice but to face him at Clooney's wedding.

"Jen's no stranger to therapy, so she decided to seek some help," a source says, according to BANG Showbiz News. "At the wedding she'll have Justin there for support, but the though of seeing Brad and Angelina is quite overwhelming. The therapist has been helping to build her confidence and eliminate the fear she seems to have built about coming face-to-face with them. She has also been having hypnotherapy."

The last time Aniston faced Pitt and Jolie was at the 2009 Oscars, when she was on stage presenting an award while they sat in the audience. The source goes on to explain that because Clooney's wedding will be so intimate, Aniston is particularly concerned about how awkward it might be when she faces her ex.
