The two single actresses met up on Christmas Eve (24.12.10) and spent the day having some girl time with Courtney's six-year-old daughter Coco.
The 'Cougar Town' actress split from her husband David Arquette earlier this year has been relying on her best pal and former 'Friends' co-star for support ever since.
A source told People: "Both Jen and Courteney are tired after a long year. They celebrated Christmas with each other and just focused on making things special for Coco."
Although they are on a trial separation, Courteney, 46, is still on good terms with David, 39, and made an effort to spend some time with him over the holidays for the sake of their daughter.
However, the chances of them reuniting are allegedly getting slimmer.
Another source said: "He's just not handling this situation well.
"He's really depressed. There was a moment when David thought they'd get back together but that doesn't seem like it will happen now and it's really tough on David."
Courteney has previously stated that no matter what happens between her and David their priority will always be Coco.
She said: "It's too early to say if we will get back together.Â I don't know what's going to happen. But we are always going to be very close and supportive and be good parents to Coco. That's the most important thing.
"We've always tried to be very open with each other. That spirit has never left us, even though things became difficult in the last year."
