This weekend, I was just lying in bed eating leftovers and streaming the seventh episode of my Castle rewatch, when I spotted none other than Meghan Markle on my screen!
Anyway, that got me thinking: What other shows have I seen with major stars in it before they were famous?
I know Gina Rodriguez once starred in Happy Endings.
And Millie Bobby Brown was on Grey's Anatomy back in the day.
Not to mention, Lin-Manuel Miranda rapped on How I Met Your Mother once upon a time!
So which celeb TV cameos have you noticed??
