Sometimes a kiss n' tell just doesn't cut it.

On Monday (July 25), Mila Kunis appeared on The Late Late Show with James Corden to promote her new comedy film Bad Moms alongside Christina Applegate. During a nauseating game of "Spill Your Guts..." — in which contestants ask other players scandalous questions round-table style with the option to either answer truthfully or eat something totally disgusting — the actress also spilled the proverbial tea clam juice on the size of her famous husband's package.

While answering Corden's question about Ashton Kutcher's penis size — "Carrot stick or beer can?" — Kunis initially answered with carrot stick.

"But beer cans are short," the actress explained, as both the talk-show host and her co-star gave her puzzled looks.

"No, not a big beer can!" the host explained, convincing her to change her answer.

"I’m thinking it’s short and stubby or long and thin. But no, [it's] like a Guinness," Kunis added enthusiastically, prompting Corden to conjure the visual of a "can of Monster," the energy drink, for the audience.

But the "Carpool Karaoke" maestro wasn't finished tormenting the the actress just yet.

During a second gag reflex-inducing round, when faced between eating a cow tongue or explaining the plot of her 2015 sci-fi bomb, Jupiter Ascending, Kunis bit the bull(et) and chose to nibble on the unappetizing muscle before her.

Watch the three play the gruesome game — if you can stomach it — below:
