It has been reported that Jennifer Aniston is asking for professional help to mentally prepare herself to face former husband Brad Pitt and his partner and fiancee Angelina Jolie at George Clooney's wedding to London barrister Amal Amaluddin, KPopstarz reported. It has been said that the highly-anticipated wedding of the most elusive bachelor in Hollywood is expected to happen later this year.

The wedding would mean that Aniston will be under one roof with Brad and Angelina, which only happened once before at the 2009 Academy Awards. Aniston separated from Pitt in 2005 allegedly because of Angelina Jolie.

Clooney recently announced her engagement with the British lawyer, and is known to be good friends with both Pitt and Jennifer Aniston. The 'Gravity' star is set to exchange his vows in a star-studded ceremony this September.

A source revealed to British magazine Grazia, "Jen is no stranger to therapy, so she decided to seek some help. At the wedding she'll have her fiancé, Justin [Theroux], there for support, but the thought 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 up about coming face-to-face with them. She has also been having hypnotherapy."

The 45-year-old actress has earlier talked about therapy and its benefits to regain happiness in life. However, she said to have never agreed on going to therapy in the aftermath of her controversial breakup and eventual divorce with Pitt. On the other hand, it has been said that the "Friends" star thinks it's different to see Brangelina together this time in a small event and that worries her.

"The Oscars were one thing, but George's wedding will involve being in a smaller, far more intimate group where they won't be able to avoid one another. Jen wants to be as breezy as possible. She has been doing role plays with her confidence coach and will be as prepared as she can be," the source claimed.

Meanwhile, Pitt's aunt, Staria, told Daily Mail that she believes the "Ocean" film franchise actor will choose his co-star to be his best man. She said, "I would say he'd choose Brad Pitt for his best man. They are good friends, I would think that's who he'd choose."
