During an interview on America's Today show, actress Blythe, 72, said she was proud of her daughter and said Gywneth, 42, does plenty of fantastic work away from the public eye.
"I know that she's the most extraordinary girl who can do everything. Incredible mother! She's raising hundreds of thousands of dollars for my husband's oral cancer foundation—things she doesn't talk about a lot. She's becoming a great environmentalist. I'm so proud of her," she said
"I think she's so accomplished that people get kind of intimidated by it. Great cook, great mum, great actress. And my son is pretty fabulous, too! A great writer."
Meet The Parents star Blythe said she was happy not to have to deal with social media when she was younger, saying: "I am so blessed that I'm old. I know how to get online. I don't know how to Twitter, toot, tweet. I don't know how to do any of it, and I don't look for it."
Blythe spent Mother's Day weekend with Gwyneth and her children - Apple and Moses - in LA before flying to New York to visit son Jake and his family.
