Jennifer Aniston And Justin Theroux Engaged? 'If He's Not Down On One Knee, It's Over!' Rumors Say
Now that the Jennifer Aniston pregnancy rumors have died down, it seems there are new speculations about the classic sitcom-gone-screen star. According to CelebsGather, the 43-year-old actress was seen with a “big rock” on her finger, leaving fans wondering if beau Justin Theroux finally popped the question.

Actresses Jennifer Aniston and Courtney Cox have been close friends since they met at the audition of American sitcom "Friends" in 1994. In fact, Aniston is godmother to Cox's daughter Coco, who is now seven years old.

However, after Aniston (who played Rachel Green on the show, while Cox was Monica Geller) met "Wanderlust" star Justin Theroux, she has found less time to keep up with other social engagements. Aniston and Theroux are now living together.

So much so that Cox was reported missing from a ceremony honouring Aniston with a star on the Hollywood Walk of Fame. According to the Daily Mail, Cox (now acting in a serial called "Cougar Town") is apparently upset after Aniston cancelled a girls' night out at the last minute, to spend the evening with Theroux.

"Jennifer's priorities have obviously changed since meeting Justin. But Courteney must feel that Jen has completely forgotten what it's like to be the single girl and that will hurt given how supportive she and David were to Jen over the years," a source told Grazia magazine.

Seems like the 20-year-old friendship is going through a hard time!
