Jennifer Aniston, Courteney Cox Fight, No Longer 'Friends': 'Cougar Town' Actress Misses Justin Theroux's Birthday Party, Former Co-Star Not in Wedding?

There are countless rumors about some sort of "Friends" reunion, whether it be a movie, a comeback season, or just a 2014 special episode. It won't happene, but the rumors still spread. But what if the stars are fighting? Will that stop the rumors? We will find out soon considering it looks like former "Friends" (in real life, too) are apparently on the outs and are no longer speaking.

This weekend, Aniston threw a lavish 42^nd birthday bash for her fiancé Justin Theroux. Plenty of friends were in attendance including Laura Dern and Isla Fisher, but Cox was not! In fact, the "Cougar Town" star was in Cancun, Mexico, with some friends. Cox eventually had to cut her trip short after breaking her wrist. This was the same day the festivities were going down at Aniston's mansion in Los Angeles.

This is not the first time Courteney didn't get an invitation to a Theroux/Aniston event. When the couple celebrated their engagement in December, Cox was not part of the celebratory crew. In fact, back in June Aniston skipped Courteney's 49^th birthday party, too. Reports claim that Thereoux encouraged his fiancé to skip the celebration in order to distance herself from her old friends.

As of now, there are very little details about Aniston's wedding, but we can probably assume that Cox will not be part of the bridal party. Yikes!

This "fight" apparently started back in 2010 when Cox and her husband David Arquette decided to separate. Jennifer and David were close friends, so she was not happy about this decision. It's a shame, too, because the former co-stars used to be very close. Aniston is actually Cox's daughter's Godmother!
