Since 2014, Sarah has been dating British actor Michael Sheen. 

It's not uncommon for comedians to delve into their personal life for material, and the I Smile Back actress does the same 

On May 17, Sarah spoke with People about incorporating her romantic relationship with Michael Sheen into her comedy routine.

'I have so much material about him, and he's always great about it. One, he's not going to like inhibit my art and my process, and I appreciate that,' she began. 

'But also because he said, "No one will ever believe that it's true. No one will ever believe that everything you're saying is exactly true." '

'So I said, "Yeah, you're right" – except now, when I'm telling PEOPLE magazine it's all true!' she said, laughing.
