Sharon Osbourne has lambasted Ashton Kutcher, saying the former Punk'd presenter is a "dastardly little thing" when asked to name the rudest celebrity she knows.
Osbourne was being interviewed with her daughter Kelly during an E!News segment when she spilled the beans.
During game 'Stir The Pot', she didn't hesitate when asked about the rudest person she'd met.
"The guy that's married to an actress and he used to do That 70s Show," she announced.
"Oh, rude, rude, rude. Rude little boy," she said.
When asked by Kelly to clarify if she meant Ashton Kutcher, Sharon replied: "Yes. Dastardly little thing."
She didn't explain any further why she had singled out Kutcher, but in 2018, she revealed he had been a guest on talk show The View which she co-presented and had upset her then.
"Bad attitude - for me. I got his name wrong so he was pissed. He comes on with an attitude, and he goes, 'What have you done in this industry'?"
Over the weekend, both Kutcher and his wife Mila Kunis came under fire for offering support to convicted rapist and That 70s Show co-star Danny Masterson.
The pair had written character letters to the judge presiding over Masterson's rape trial, the details of which were revealed on the weekend following Masterson's conviction.
In a video released, both Kunis and Kutcher apologised for any offence they had caused, and reiterated their support for victims in sexual violence cases.
"We are aware of the pain that has been caused by the character letters that we wrote on behalf of Danny Masterson," Kutcher said.
"We support victims. We have done this historically through our work and will continue to do so in the future," his wife, Kunis, added.
