The pair was chatting during some downtime on the set of their hit Tv crime drama when Tunney suddenly fell sick, and Baker had to dodge the vomit.
However, the illness didn't stop the actress from continuing their talk afterwards.
Baker explains, "She vomited on me. It's actually quite pleasant and I feel closer to her! She was sick at work and she's one of the great humans, she's such a trooper, her work ethic is incredible. Sometimes you work hard, sometimes you're not feeling so great, you're at work, and I was mid-conversation with her and it was incredible charming and I've never seen anyone do it - in mid-sentence, she threw up and I had to (swerve), it was like The Matrix.
"She was like, 'I'm so sorry! Anyway...' She finished the conversation!"
