The 54-year-old actress took home the Emmy for Best Lead Actress in a Comedy Series for her portrayal of Selina Meyer on Veep on Sunday night -- her fourth Emmy win in the category, now tying her with both Mary Tyler Moore and Candice Bergen for most lead actress Emmy wins ever -- but her co-stars joked with ET that working with such a decorated actress comes with its cons.
"She's a nightmare. She should never have a job," Tony Hale joked.
"She's awful -- you can't look her in the eye," Matt Walsh added. "She has her own lunch table ... she will never do off-camera lines with you. The minute she says her last lines she drives home. She's pretty bad."
But it's Anna Chlumsky that clearly had the best analogy.
"I wonder every day whether we'll all be alive at the end of the day," Chlumsky joked. "It's one of those .. did you see Whiplash? Yeah, it's like that."
Though in all seriousness, the tight-knit cast obviously love the hilarious former Seinfeld star.
"She's amazing and we love her, and she's a team player," Chlumsky gushed. "We're an ensemble -- I mean, she's number one, she's the president -- but we're so thrilled to be her staff."
"You know, you kind of hear these ideals of what Hollywood starlets are and they're kind of arrogant, whatever, she's so normal," Hale echoed. "Family's her first priority, it's not this business and ... she's one of the most hilarious women I've ever worked with."
ET's Nancy O'Dell caught up with the mother-of-two herself backstage at the Emmys, where the funnylady said it was "mindblowing" to accept her fourth win. Louis-Dreyfus beat out Edie Falco, Lisa Kudrow, Amy Poehler, Amy Schumer, and Lily Tomlin for the award.
"It was great, I was really nervous I felt -- it was very stiff competition, maybe the stiffest ever," she said. "All those girls in this category are just so extraordinary and I don't know, I'm just so overwhelmed, it's great. I cannot believe… I'm surprised that I won again this year to be honest."
