At the second season premiere of her Hulu show the "Difficult People," Klausner claimed that the 43-year-old Oscar-winning actress is like most of Hollywood "fake", reported Ace Showbiz.
"They pretend that they are (all great friends), but the stuff that is said about people behind the scenes is really terrible. Well - Gwyneth Paltrow - there's many a tale to tell. All kinds of backstabbing," Klausner, 38, said.
Klausner did not give out specific details on her claims about "Iron Man" actress.
