Sarah Silverman will never marry.

The 43-year-old actress - who is in a relationship with 'Masters of Sex' actor Michael Sheen - has laughed off reports she is desperate for the actor to propose, insisting she finds the institution of marriage ''barbaric''.

She tweeted: ''Just read that I wanna get married which is hilarious b/c I will never get married.

''Why would I want the govt involved in my love life? Ew. It's barbaric.(sic)''

Sarah - who previously dated Jimmy Kimmel for five years - spoke out following an article which claimed she had been leaving ''pictures of engagement rings all over the place'' in a hint that she was ready for Michael to propose.

And the brunette star - who began dating the 45-year-old actor at the beginning of the year - branded the claims ''bigoted''.

She wrote: ''''That s--t never bothers me b/c who cares but I feel like this one is bigoted.

''The Jew girl MUST want a RING! Yich.(sic)''

Sarah - who is vegetarian - previously compared marriage to eating meat, saying it was ''gross and f***ing crazy''.

She said: ''It's just not for me. I'm a vegetarian, but I don't have a problem if you want a hamburger. Marriage, to me, is like eating meat. I think it's gross and f***ing crazy. It's this superbarbaric, old-timey tradition that no one remembers we don't have to do anymore.

''I really do believe in love. I've experienced it, I've had it, so I know it's real.''
