Gwyneth Paltrow: 'People are so mean to me'

Gwyneth Paltrow doesn't care if you don't like her.

Though the actress, 38, has caught flak for her lifestyle newsletter, GOOP, she's still dishing out the advice.

"Any time you do anything with any degree of sincerity, people make fun of you," she tells the March issue of Harper's Bazaar UK. "That's totally fine. I don't care. I don't read any of it. My thing with Goop has always been, if you don't like it, then don't log onto it."

The star does admit, however, that she did contemplate pulling the plug on the site.

"There were a couple of times when I thought 'I'm just gonna stop doing it. People are so mean to me. I don't want to do it,'" she says. "But then I was like, 'Who cares what some lame person out there says?' I was in Italy once, and this old man came up to me and said, 'I had the best time in Nashville because of Goop.' And that is so worth it to me.”

It helps that the married mom of two has plenty of pals — including some very famous ones, like Beyonce, who gave her advice for her role as a singer in "Country Strong."

"Beyoncé is the most talented human being on the planet," Paltrow gushes to the mag. "She has so much mastery over what she does. It's not even confidence — it's on a whole other level. It's mind-blowing. I watched her [perform] a lot to see how she did it, and I was like 'S---! I can’t do that!'"

The actress adds that her "Iron Man" costar, Robert Downey Jr., also gave her some tips for her performance as an ex-drug addict.

"Alcoholism is such a vicious cycle and Robert really helped me understand it," she says. "I understand how you can do something bad for you because I smoked forever. I smoked even when my dad had throat cancer. I was like 'I know this is probably going to kill me, but I'm going to smoke it anyway.' But I didn’t understand wrecking other people's lives, and then kind of just waking up and tying your shoes. So he helped me figure that out."
