Mila Kunis got up close and very personal with the Late Late Show host, James Corden, 37, when she revealed the size of her husband Ashton Kutcher’s manhood to him.

The 32-year-old beauty was promoting her new movie, Bad Moms, but it was the discussion she had about her hubby’s privates, that stole the show Monday, July 25.

Both Kunis and her costar Christina Applegate, 44, were invited to play the British host’s new game "Spill Your Guts or Fill Your Guts," which involves a revolving wheel of disgusting food and drinks that they have to consume if they don’t answer the questions.

But when the pregnant mom-of-one, was faced with either drinking clam juice or revealing whether Kutcher, 38, has a "carrot stick" or "beer can," she chose to answer.

“I have to have one or the other?” she asked.

Informed that she had to make a decision, she quipped, “Carrot stick. Beer cans are short,” before changing her mind.

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

Kunis didn’t escape the foul foods entirely, though, and was forced to eat a piece of cow tongue when she couldn’t answer what her box-office flop Jupiter Ascending was about.

Corden, meanwhile, had to tuck into some revolting calf’s brain to avoid revealing his least favorite "Carpool Karaoke" guest.
