Bona fide funny man Will Ferrell appeared on Watch What Happens Live with Andy Cohen, and as always, the tea was spilt.
Will is promoting his new movie with Amy Poehler, The House, and the diva queen herself, Mariah Carey was set to make a cameo in it… buutttt it didn’t go as planned.
Known for her antics, Andy if it was because she would show up four hours late to set, in which Will answered… “True.”

Or, how her only notes for the scene would be, “I don’t want to do the scene.” Yikes.
“Even though it was totally approved ahead of time,” Will added.
When Mariah was set to sing one of her songs, she decided she wanted a different one… which production didn’t have the rights to use.
“It was quite a kerfuffle,” Will revealed. “A sh*tstorm.”
But one of the most outrageous requests that came from Mariah was when she asked for an abundance of stuffed lambs in her trailer for her “Lambily” which is the nickname given to her fans. Lol. What?
We’re like, 3,000% sure when Mariah sees this shade she will admit she doesn’t even know Will, but ’til then, watch the entire interview below!
