If the apple doesn't fall too far from the tree, then these seven pregnant celebrities are likely carrying the next generation of green activists.
From Alicia Silverstone to Natalie Portman to Pink, it seems this year's due dates -- which range from "any time now" to later this fall -- belong mostly to a group of women who've made a point of incorporating sustainable living into their kid-free years.
1. Alicia Silverstone
The "Clueless" actress knows a thing or two about the green life: Along with posing for PETA and launching her own line of eco-friendly makeup brushes, Alicia Silverstone's lifestyle book The Kind Diet was just released in paperback (on recycled pages with soy ink, of course).
But when is the big day? Silverstone and her husband, Chris Jarecki, announced the pregnancy on her blog in January but didn't give a due date.
2. Natalie Portman
Portman, who designed and launched her own line of vegan footwear in 2008, also took a turn judging "Project Runway" designers on their eco-friendly creations -- and stepped in for a meatless challenge on "Top Chef."
And if her little one is interested in the Hollywood scene, he or she could end up singing about recycling just like Portman did in her pre-starlet days.
3. Jessica Alba
She'll need that nursery again when her second child with husband Cash Warren arrives later this year -- but the rest of their house is ready for the newest addition to the green family: Alba has said she drives a Prius, recycles, and is working on eco-friendly renovations throughout her home.
4. Marion Cotillard
Actress Marion Cotillard has been an environmental advocate since her childhood in the French countryside.
"I'm very happy with what's happening now and how the awareness is spreading," she told Interview magazine last year. "Because 10 years ago my mind-set wasn't really normal for most people. I sounded like a crazy person talking about the environment. People saw me as a hippie who wanted to make my own cheese and live with animals in a house without electricity."
She and her boyfriend, Guillaume Canet, are expecting their first child this spring.
No matter what name they settle on, the baby will no doubt share the vegetarian singer's passion for animal rights: Pink has appeared in campaigns for PETA, including an anti-fur PSA with Ricky Gervais and a boycott of Australian wool.
6. Alyssa Milano
The actress and her husband, Dave Bugliari, announced the pregnancy in February and told People that their bundle of joy is due in "early fall."
7. Emily Deschanel
"We can all be effective animal advocates by simply adopting from a shelter or rescue group, refusing to wear fur, or going vegetarian for at least one day a week," she told Mother Nature Network.
Deschanel and her husband, David Hornby, announced the impending birth of their first child at the end of March.
