Michael Sheen and Lizzy Caplan are a cute new couple!
We guess it's hard not to create some sexual tension co-starring on a show called Masters Of Sex because these two began dating shortly after!
And if they were seeking a friend for the end of the world, they were just in time! The couple was spotted checking out the Hollywood premiere of The Worlds End on Wednesday night!
But to hook up with her Mean Girls costar? Doesn't that violate some sort of actress bro code?
