The latest Goop newsletter features an array of green products to use in order to safely clean your home.
The All-Purpose Cleanser received a just passing grade of C—that's not exactly what we would call a stamp of approval.
During the newsletter introduction, Paltrow explained that she's reevaluated some of the items she's used in her home—especially when it comes to cleaning products.
"Many of the 'clean' products I proudly use (and have even touted on goop) have turned out to be a product of marketing, rather than actually safe," she wrote.
The famous ladies aren't very close, however, they're not really sworn enemies either.
But last year, when Alba was promoting her book, The Honest Life: Living Naturally and True to You, major shade was thrown at the blond Oscar winner.
When asked if her book was partly inspired by Paltrow, Alba was quick to separate herself from the Goop creator.
"Gwyneth Paltrow probably lives a very similar lifestyle, but I didn't grow up with a bunch of money, so my tips are much more grounded: repurposing things and making things at home," the mother of two told the New York Daily News. Oh, snap!
So far there's been no response from The Honest Company or Alba herself regarding the Goop review, so only time will tell how this fancy lady feud will turn out.
