"I feel there's something slightly misogynistic about it," she said.
Paltrow continued the interview and broke down why reporters should stop comparing the actresses turned entrepreneurs.
On Alba's The Honest Company, she said: "Jessica, especially, who's a friend of mine -- our businesses could not be more different. There's not a lifestyle piece to her business. The fundamentals of our sites are very different."
This doesn't mean the Iron Man actress isn't supportive of her friends. "This is a common theme. I think Reese and Jessica and I -- I don't know Blake Lively, and I don't know if Jessica and Reese know each other -- I'm friends with both of them and I speak to both of them and I want to do everything I can to support their businesses. I'm not articulating it well, because I haven't completely worked out what it is, but I feel very proud when Jessica was on the cover of Forbes."
Paltrow has said she will stop filming in 2015 to focus on the expansion of Goop.
