WATCH: 'Ozark' star impersonates Gwen Stefani and Britney Spears

If you're obsessed with Netflix's Ozark like I am, you might know her as Ruth Langmore (she was also in another one of my favorite TV series over the past few years, FX's The Americans)... but actress Julia Garner showed off some impressive impersonation skills with Jimmy Fallon last night!

Early in their chat, she revealed she's married to Foster the People's Mark Foster - that was news to me.

But at around 3:30 in this video is where the pop star impressions begin. Enjoy!
