Mandy Moore and her family are "doing well" after their home was left badly damaged in the Los Angeles wildfires earlier this year

She told Extra: "She's doing well. I mean, thank goodness.

"A lot of the structure was able to be salvaged, which is great, but it's so jarring. It's so life-altering, and she has children and pets. It's just frightening because there's nothing you can do but hopefully get out of there."

Chrissy says she keeps in touch with all of her co-stars from the hit NBC drama - the cast of which also included Milo Ventimiglia, Justin Hartley, Susan Kelechi Watson, and Chris Sullivan.

She said: "Oh, my gosh, everybody. We all are texting each other. I always text when any projects come out or Sterling with his nominations for 'Paradise.'"

Chrissy added of Sterling K. Brown (her onscreen sibling): "Oh, he's the best. I really feel like he's a big brother for me."

Chrissy's update on her co-star comes after Mandy recently paid tribute to her mother-in-law Kathy Goldsmith, describing her as the "silver lining" amid the devastating wildfires.

As well as Mandy's home suffering damage, Kathy lost her abode.

She wrote on Instagram: "It's been a hell of a year and my Mother-in-law, Kathy, has risen to the occasion in every way. Selfishly, I'm not sure what I would have done without her in the hours, days, weeks, and months since the fire. She suffered her own immense loss and has been by our side since the very beginning, without skipping a beat. I'm heartbroken that our 5 min walk to her house is no longer on the table BUT so grateful that we've been able to live under the same roof these last 6 months- if there's any silver lining in this whole thing, she's definitely ours. (sic)"

Mandy heaped praise on Kathy for "absolutely mastering" the childcare of her and Taylor's three children, admitting the couple "couldn't be luckier that she's ours".

She added: "From coffee in the morning as we let the dogs out, to tea after the kids go down and talking about our grief, funny things that happened in our day, etc.... To her absolutely mastering bath time, mealtime, playtime and everything in between- including moments like when Gus dec lared today- "I have to GO POOP with Gaga now!", we couldn't be luckier that she's ours and we're never letting her go.

"Seriously, she thinks she can move into her new place but that's not happening. Ha! I know you want this Birthday to just move right along, but those of us that know your friendship and heart are MORE THAN HAPPY to celebrate you today and always.

HAPPY BIRTHDAY, @kathy_goldsmith!! We Love you, Gaga!! Xo (sic)"

Mandy recently admitted she is "looking forward to rebuilding" her family home following the fires.
