It looks as though Jennifer Aniston might be forced to run in to her ex-husband Brad Pitt and Angelina Jolie as there are new rumors suggesting that Hollywood's A list will be jetting off to Lake Como, Italy this weekend.

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

According to Naughty But Nice Rob, Clooney's fiancé Amal Alamuddin and her mother were both seen visiting his Italian villa last week and now his parents are also at his home. With both families in town, many are speculating that the big wedding might only be days away.

Despite the fact that everyone is town, a source tells the gossip site that the wedding won't go on unless of course there's one special guest present for the ceremony.

"Both families are getting to know each other better and they are all excited about the wedding," the source explains. "However, you will know when they are getting married when you see Matt Damon in Italy."

Meanwhile, it was earlier reported that Aniston was suffering from panic attacks in anticipation of meeting both Pitt and Jolie 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 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 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.

Aniston is also planning her own wedding with fiance Theroux for later this year. The couple announced their engagement in August 2012.
