Alexandra Daddario is already getting some parenting advice from her Mayfair Witches costars!

After announcing earlier this month that she's expecting a baby with husband Andrew Form, the Mayfair Witches star, 38, joined her cast mates at San Diego Comic-Con 2024 on Saturday, July 27, to dish about the AMC show and how her costars have been supporting her.

As Daddario tells PEOPLE, she's already gotten some parenting advice from costar Harry Hamlin, but when asked about his advice, the 72-year-old used the opportunity to share a few jokes. "Parenting advice? Well, don't spank em'," Hamlin says, before Ben Feldman chimed in: "That's cast advice, too, right?"

After Feldman, 44, offered his own advice to "raise supermodels" — referencing Hamlin's model daughters Delilah Belle and Amelia Gray — Hamlin told Daddario that Amelia, 23, "raised herself."

"I'm not the guy to ask advice from, please," he adds.

"In all seriousness, I've already asked Harry for advice," Daddario says. "He has great advice. He's a wonderful father, so I've learned a lot."

Hamlin shares his daughters with wife Lisa Rinna and is also dad to son Dimitri Alexander, who he shares with ex-partner Ursula Andress.

With Daddario pregnant, her Mayfair Witches costars also told Entertainment Weekly what it was like to see her stay home as they went out partying in New Orleans and Dublin while filming season 2. Feldman explained that she had "a giant secret" and was "at home with her secret every night."

"She would say excuse me for a minute, and she'd walk off set and [vomit]," Hamlin told the outlet, as Feldman added, "Which is so cool when you're the love interest."

"One time I threw up right outside my trailer, and my best friend had to hose it down," Daddario said. "I was like, 'Can someone get me a sandwich please? And no cold cuts please?' Ben was like, 'Are you pregnant? And I’m like, 'That’s none of your business, and by the way, get me some watermelon.' "

Feldman also recalled Daddario telling him "I don’t know" when he asked if she was pregnant. "How that was kept a secret is stunning to me," he said.

“It’s long and complicated, so I don’t want to be too specific,” she told Vogue. “Those kinds of losses and trauma are very hard to explain unless you’ve been through them. I really relate to all the women who have been through those kinds of things in a way that I didn’t understand fully before. It’s very, very painful.”

The next season of Mayfair Witches arrives on AMC and AMC+ in 2025.
