Courteney Cox celebrated Jennifer Aniston’s birthday last week at the famed Roosevelt Hotel’s Spare Room.

The $5,000 venue was the perfect place for Courteney Cox to join Aniston in ringing in her 46th birthday.

The birthday bash was full of Aniston’s A-list friends. Besides Courteney Cox, guests included Jennifer Aniston’s long-time fiance, Justin Theroux, as well as her famous couple friends, John Krasinski and Emily Blunt, and Isla Fisher and Sacha Baron Cohen.

Also in attendance was Tobey Maguire, Jennifer Meyer, Ken Marino, the fabulous Amy Adams, Lake Bell, and Jennifer Aniston’s hairstylist Chris McMillan.

Courteney Cox, Jennifer Aniston, and all of the other guests enjoyed bowling at the room’s double lane, as well as backgammon, chess, monopoly, dominos, and playing cards.

The party, which lasted from 9 p.m. until 1 a.m., was “pretty laid back”, according to a source.

However, Courteney Cox had everyone a little concerned when, on the same day as Jennifer Aniston’s birthday party, she was spotted having a bit of an emotional breakdown while talking with a friend outside of a Starbucks.

Some have speculated that the only thing that could cause her so much pain must have something to do with her fiance, Snow Patrol rocker Johnny McDaid.

Courteney Cox became engaged to McDaid last year.

Courtney Cox revealed on a September episode of Jimmy Kimmel Live! that his proposal was incredibly sweet and involved her 10-year-old daughter with David Arquette, Coco.

“He gave her a little diamond ring and got on his knee,” Courteney Cox said. “And she said, ‘Great! I’m going to camp tomorrow. Let’s do it right now!'”

So, Coco and Johnny McDaid planned to do it at Coco’s birthday party, thrown by none other than Jennifer Aniston.

Courtney Cox elaborated, “They made a plan to count down from three, and when they got to one, he was gonna get down on his knee and say, ‘Will you marry me?’ and she was gonna say, ‘Will you marry him?'”

She added, “They planned it out, they found the perfect tree, with three branches that led to one trunk — it was just beautiful.”

That is lovely. Hopefully Courteney Cox’s tears aren’t a sign that something has gone awry in her relationship with Johnny McDaid.

What do you think Courteney Cox could be so upset about on the day of her BFF’s birthday party?
