Courteney Cox is still one of Jennifer Aniston's closest friends.

The 'We're the Millers' actress, who split from Brad Pitt in 2005 after five years of marriage and is currently engaged to Justin Theroux, has regularly sought refuge at her former 'Friends' co-star's house in Los Angeles during difficult times in the past.

Speaking about their 20-year friendship, the 44-year-old star told More magazine: ''There's absolutely no judgment in Court. You'll never feel scolded. She's extremely fair, ridiculously loyal and fiercely loving.''

She added: ''I've slept in her guest bedroom a lot. Without giving away too much of my private stuff, all I can say is she's been there for me through thick and thin.''

Jennifer and Courteney were rumoured to have ''drifted apart'' last year but have been spotted hanging out together again in recent months.

Courteney's other former co-star Lisa Kudrow, 50, also still counts the brunette beauty, 49, as one of her favourite people.

The 'Scandal' actress aid: ''There's no agenda. There's no guile. There's no game. You can trust her completely and fully. Whether I see Courteney every week or once a year, it doesn't matter. I know who she is, and I know where I stand.''

It was previously rumoured that Courteney was trying to convince Jennifer to reunite with their former castmates, Lisa, Matt LeBlanc, Matthew Perry and David Schwimmer, for a reunion special of 'Friends.'

But Matt, 46, recently said it was unlikely, adding: '''Friends' was about a finite period of time in your life, like after college but before your life really started. And that was the magic of it. It was that point, that time in your life.''
