These days, it seems like half of the people in Hollywood are super-ostentatious hipster vegan environmentalists. Gwyneth Paltrow was ahead of the curve in that respect, and she managed to get on everybody's last nerve by talking about it as often as possible. She's also into new-age holistic therapy practices like transcendental meditation and cupping, and even managed to be pretentious about announcing that she was filing for divorce from her first husband Chris Martin, describing the process as 'conscious uncoupling.'
It's the high degree of pretentiousness that puts people off Paltrow, but that's a little unkind. She's not actually doing anybody any harm (other than perhaps herself with the cupping!), and her seemingly unusual beliefs go hand in hand with plenty of charity work and philanthropy. Paltrow is an ambassador for the charity 'Save the Children', as well as sitting on the board of the 'Robin Hood Foundation,' which combats poverty in New York.
