Former Friends star Jennifer donned a sweater containing Ellen's Insta-Breasts invention during an appearance on The Ellen DeGeneres Show, which gradually grew bigger and bigger during a Q&A segment.
Playful Jen went with the joke, insisting she didn't see any difference as she casually sipped her tea and straightened her jumper.
Um, well we all do!
Jen, 45, then stood up to give the audience a good look, joking: "This is my version of the Kim K. The forward one!" That, of course, was a reference to Kim Kardashian's rather famous and rather large bottom.
Just last week, Jennifer had joked about Kim's naked photoshoot for Paper Magazine, saying she'd actually done it first when she posed nude on the cover of Rolling Stone.
The major difference, though, was Kim went full frontal naked for Paper while Jen was rather more demure, flashing just a cheeky hint of bum.
