If blondes really have more fun, these two are living proof.
So, when Amy recently did a cover interview with Vanity Fair, they were keen to hear more about her relationship with her new friend and inspiration.
As part of the interview, Amy appeared in a video watching J-Law interview clips - and sharing if they were true or false.
Among the criticisms, Amy called J-Law the meanest person she'd ever met (guys, that's probably, most likely, maybe not true!) and revealed the Oscar-winning actress had once urinated in a bidet.
Also, in case you were wondering, a bidet is a restroom feature that is for "washing your a**hole".
Watch the clip here:
Last year it was revealed Amy and Jen were teaming up to write their own - probably side-splitting - movie, in which they will play sisters.
In a previous interview, Jen said they were "made for each other."
"Amy and I were creatively made for each other. We have different flavours. It’s been the most fun experience of my life. We start the day off on the phone, laughing. And then we send each other pages. And we crack up.
We can't wait to see the finished product!
