Not that their reactions were subdued. "[We're] so excited," said Betty star America Ferrera at Monday's New York City premiere of her movie Sisterhood of the Traveling Pants 2.
"I'm so happy for them," gushed Ferrera, 24. "They're going to be the best parents. I don't think there could be a more wonderful father to girls."
As for her own expectations of the arrivals, who are due this winter, Ferrera added, "I just am waiting to see how tall those girls are going to be. I think they're going to be born my height."
Vanessa Williams has even started shopping. "I've already gotten them organic cotton baby clothes from Green Babies to start them off right," Williams, 45, told PEOPLE. "Rebecca is glowing, and Jerry will make a really fun daddy."
"She was more excited than you can imagine. Jerry's a great guy. And they laugh so much, and they have so much fun together," added Becki Newton, who also noted that the stork seems to be an honorary cast member on the show.
Besides Romijn, Eric Mabius is expecting his second child come fall, and Christopher Gorham's third is due in January.
Romijn's 'Mama-Bear Thing'Costar Ana Ortiz says Romijn is "blissfully happy" to be expecting two babies. "She's such a mom already. She has that Mama-Bear thing, always watching out for us, and she's a hoot," says Ortiz. And the dad? "Jerry is going to spoil them completely rotten."
"They're not going to be the uptight kind of parents, 'You can't do this, you can't do that,' " ventured 14-year-old Mark Indelicato, who plays Justin Suarez on the show. "They're going to be awesome parents. They love to have fun. But they still have boundaries. And they live in the coolest place ever in L.A."
And, as the parents-to-be should also note: "I'm a cheap babysitter," says Indelicato. "I only charge five bucks an hour."
