Hey Barbie! Hey Ken! Margot Robbie (Barbie herself) and Ryan Gosling (just Ken) speak to Ali Plumb about Greta Gerwig's Barbie, touching on such hot button topics as the Barbie slide, the Barbie wave, Barbie memes, Ken's rollerskates, Ken's tricky-to-say fashion pieces and Ken's totally unimportant t-shirts. Oh, and those times Margot and Ryan dressed up as a cigarette and a hamster (respectively). And that's not forgetting Greta herself, as well as America Ferrera, Simu Liu and Issa Rae, who are all on fine, fine form.
