Jennifer Aniston Pregnant Rumors Swirl as Starlet 'Reveals' Bridesmaids: Chelsea Handler, Emily Blunt, No Courteney Cox?

The pregnancy rumors surrounding former "Friends" starlet Jennifer Aniston never seem to end. First, several gossip tabloids claimed that the stunning 44-year-old starlet underwent "extensive fertility treatments" with fiancé Justin Theroux, and now she's suddenly expecting twins (a boy and a girl, to be exact). In the most recent shady "baby news" report, Ok! magazine insists that Theroux surprised Aniston for her birthday with plans to design a luxurious nursery for their two future newborns. While fans ponder that seedy report, other sources reveal that Aniston has finally chosen her official bridesmaids... and apparently Chelsea Handler and Emily Blunt made the cut, while good friend and co-star Courteney Cox did not. Are readers buying all of these rumors so far?

Aniston recently celebrated her 44th birthday on February 11, and according to an alleged inside source for Ok! magazine, "Jen can't wipe the smile off her face. She had a great day - and night!"

The "pal" goes on to reveal that on her b-day, fiancé and fellow co-star Theroux showed up to Aniston's movie trailer with a beautiful bouquet of pink roses. He had a private dinner arranged and presented her with a stunning vintage Cartier watch. All sounds well and good, until the pregnancy rumors add a little eyebrow-raising twist to the romantic birthday celebrations:

"He hired a set designer from Zoolander to come up with ideas for the nursery [for twins]," the source claims.

Funny thing is, several sources continue to deny such pregnancy claims. According to Gossip Cop, Aniston is NOT expecting twins. Therefore, it's highly unlikely that the couple is planning on designing a five-star nursery for two. Add that sensationalized gossip story to the list of bogus Aniston-Theroux baby reports:

Meanwhile, other reports allege that Aniston is busy planning her wedding... and the names of her chosen bridesmaids were recently leaked on the web. Actress Emily Blunt and comedian Chelsea Handler made the cut... apparently, fellow "Friends" gal pal Courteney Cox did not:

"Now Jen is with Justin, things with Courteney are different. Jen wants to include some of her new pals and, though she will attend the wedding, she thinks that Courteney may have too much on her plate. Aniston thinks that Chelsea is brilliant. She's the only friend who publicly defended her over Angelina Jolie getting together with her ex Brad Pitt in 2005, so there's fierce loyalty there." 

Yeah... this same source claims that the duo is set to get married within "weeks" and Aniston wants to keep the date secret - but it'll probably be sometime after the Oscars. Oh, and she's apparently inviting her estranged mother Nancy Dow and her former mother-in-law, Jane Pitt.

Are Mstarz fans buying any of these rumors?

Until Aniston goes into labor or walks down that aisle, nothing can be proved.
