Laurie Metcalf has worked with a ton of celebs over the years, but who has been the biggest diva on set?!
The actress stopped by "Watch What Happens Live" on Thursday night, where she was grilled on her famous former costars.
The Hollywood veteran starred alongside Roseanne Barr on "Roseanne" from 1988-1997, and she saw her fair share of outrageous behavior.
In fact, she told host Andy Cohen that extreme measures were taken when Roseanne was "too lazy" to get to set.
"Sometimes she said she didn't want to walk on set, so we had a motorized wheelchair for her," she revealed.
As for her experience working with Lindsay Lohan on "Georgia Rule," Metcalf admitted that Lilo was less than professional.
On a scale of "1 to Hot Mess," Laurie said, "I was there on a mess day. She didn't come out of the trailer."
Lohan was slammed by the head of the company producing the film for calling in sick after "heavy partying." She was called "irresponsible and unprofessional" for refusing to shoot her scenes.
Looks like it Laurie had a front row seat!
During the segment, Metcalf also talked about working with Madonna on "Desperately Seeking Susan." Check out the clip below to find out what working with the music icon was really like!
