‘A beer can’ Mila Kunis compared Ashton’s penis to a GUINNESS

While once known for her notoriously private nature, Mila Kunis has turned that particular perception on its head after recently offering some particular interesting insights into the relationship she shares with husband Ashton Kutcher.

Just last week, the Black Swan star revealed that she and Ashton had started out as the classic 'friends with benefits' before graduating to fully-fledged boyfriend and girlfriend status.

And this week, she decided to give viewers of The Late Late Show an idea of what she's dealing with in the bedroom department when it comes to her husband's junk – yes, really.

During the Spill Your Guts or Fill Your Guts segment of the popular late night chat show, the 32-year-old actress revealed that her husband's penis most closely resembled our father's favourite weekend tipple.

After being presented with two options – a carrot stick or a beer can – Mila initially opted for a carrot stick before changing her mind.

“I have to have one or the other? Carrot stick. Beer cans are short," she answered before realising she may have sold her husband a little bit short on the girth front.

"Oh, beer can, beer can…I was thinking short and stubby and long and thin. But like a Guinness," she eventually concluded.

Well hello, Ashton…
