Andy Cohen/Instagram Although many celebrities have their opinions, former Real Housewives of New York star Carole Radziwill went the extra mile with her theory. “Henry is too obvious. Husband is also. I think it’s that blonde friend of Nicole’s. The lawyer,” she wrote in an interaction highlighted by Comments by Bravo. “As a writer I’m thinking why is she even a character at this point unless…” “And as a former RHONY I know something about female friendship betrayal. It’s always epic. Girls, we know that’s the ultimate betrayal. That’s my vote,” she continued, before admitting, “But I could be wrong and it’s the husband.” Nicole Kidman and Hugh Grant in The Undoing.

However, Cohen wasn’t convinced that her character has what it takes for reality television. “Grace might be too secretive and bottled up to be a good real housewife!” he wrote on his Instagram Story.

I love white mess,” Rae joked. “My mom made us each write down who we think the killer is on a piece of paper and has locked it away until after the finale!!!!” Washington added, to which Kidman replied, “Love your Mom’s idea.” Kidman’s other favorite post came from Kourtney Kardashian, who captioned a recent series of photos: “Who killed Elena Alves?” “I have a few guesses,” the actress coyly replied. Kidman's costar Edgar Ramirez also got in on the fun and responded to some fans, including director Ava DuVernay. Issa Rae, Kerry Washington and Nicole Kidman. Nicole Kidman/Instagram Although The Undoing has been a hit with fans, the limited series will likely be done after the finale airs. "This is a tight story, which is why I think six hours is perfect," director Susanne Bier told Entertainment Weekly. "It's not like a drama series where you're not quite sure how they're going to evolve and you have a next season," added Kidman. "That's why I say it's like cinema, because you have a beginning, middle, and end. The thing about a limited series is it's so difficult because you're writing a much longer form of cinema that you have to keep people engaged in, and in some ways that's so much harder. That, as an actor, is delicious." The Undoing airs Sunday at 9 p.m. ET on HBO.
