Courteney Cox’s obsession is revealed by Jennifer Aniston.

Courteney Cox and Jennifer Aniston got along well on the Friends set for years, and according to Aniston, Cox is a “neat freak.”

In a vintage interview with Marie Claire, the Emmy winner discussed her friend’s cleaning compulsion and love of a well-organized home.

The 55-year-old said the actress had always been a fan of the co-star’s line of beauty products for homes, Homecourt.

“Well, woman, what the heck took you so long, I’m wondering. Literally, this is your wheelhouse,” she continued.

Jennifer laughed as she recalled how meticulous she was about keeping things clean: “The amount of times I’ve found her on the floor, on all fours, scrubbing something — every time I enter her house.”

Speaking of friends, the We’re the Millers actress filmed a steamy scene for The Morning Show with her celebrity friend Jon Hamm.

Prior to the hot and heavy scene, the pair was made to feel at ease, according to the series’ director Mimi Leder.

The elderly gentleman stated to Variety, “It was a closed set and two very grown-up actors who really understood the nature of the storytelling and were very much a part of it.”

We wanted it to be sensitive, she continued. It was supposed to be sexy. We desired an adult atmosphere. We wanted people to feel something. They let go completely. They both excel as actors. There you have it, then.
