Blythe Danner thinks people are ''intimidated'' by Gwyneth Paltrow.

The 72-year-old star believes her Oscar-winning actress daughter, who also runs her own lifestyle brand Goop, only attracts a lot of criticism because she is ''so accomplished'' and successful.

The 'I'll See You in My Dreams' actress said: ''I'm so proud of her. I think she's so accomplished that people get kind of intimidated by it.''

Blythe, who husband Bruce Paltrow died from cancer in 2002, also claims the 42-year-old actress, who has daughter Apple, 10, and son Moses, nine, with ex-husband Chris Martin, is becoming a ''great environmentalist'' and is secretly very selfless.

She told the 'TODAY' show: ''I know 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.''

The 'Meet the Fockers' star previously praised Gwyneth and Coldplay frontman Chris for the way in which they handled their split in March 2014.

She said: ''They are so smart...both incredibly brilliant. They're making it work, they're great friends and the kids are in wonderful shape. So I have to take my hat off to both of them.''
