Sarah Silverman claims Michael Sheen ''classes [her] up''.

The 'Master's Of Sex' actress has joked that she pulls her partner - who she started dating in 2014 - ''right down to [her] level''.

She shared: ''He really classes me up and I just pull him right down to my level unfortunately for him. I could go on and on.''

The 44-year-old comedian also went on to gush about her ''sexy, gorgeous and astoundingly brilliant'' co-star Michael, before joking she'd forgotten his name.

Speaking on Bravo's Inside the Actors Studio, she she said: ''Bill Masters is played by the sexy, gorgeous, astoundingly brilliant - I'm just stalling because I can't remember his name ... Michael Sheen, who is also my real-life lover.''

Meanwhile, Sarah recently admitted she is in her ''sexual prime'' and has become an ''animal'' in the bedroom.

She explained: ''As I get older, it really is true what they say, that you get in your like - not to be gross - but, like, sexual prime. You know, you turn into like an animal ... I wish he was here. I sent him a picture of my boobs and I was like who's going to help me out of this dress? And now he wishes he was here!''
