There must be something in that Hollywood water, because multiple celebrities are expecting children this year, ranging from reality TV star Kourtney Kardashian to “Avatar” actress Zoe Saldana, who is expecting twins. Below is a quick rundown of the stars who expect to welcome babies in the coming months.

Fans were shocked to find out the “That '70s” star was pregnant with her former co-star's baby. She and Ashton Kutcher played a couple on the hit show, but after he married Demi Moore it seemed like a real-life happy ending for the duo was over. Things for Kutcher and Moore didn’t work out, though, and after some time on the market, the “Two and a Half Men” star started a secret relationship with Kunis. The two are now engaged and will reportedly name their little girl “Finn,” according to a source from Radar Online. It’s apparently a nod to Ashton’s grandmother, whose maiden name is Finnegan. When asked about her due date, Kunis said only it was “sometime this year.”

Kourtney Kardashian

Kourtney Kardashian shared that her family of four would grow to five after she discovered she was pregnant for a third time. The oldest sister from “Keeping Up with the Kardashians” has shared various pictures of her burgeoning belly on Instagram and even put on a gold bikini so followers could see her full baby bump. She, longtime boyfriend Scott Disick and their two children Mason, 4, and Penelope, 2, have been in the Hamptons filming a spin-off of “KUWTK.”

Zoe Saldana

Zoe Saldana famously dated Oscar nominee Bradley Cooper, but the “Avatar” actress has clearly moved on with husband Marco Perego. She hasn’t confirmed the pregnancy, but from the looks of her baby bump it seems evident she is with child. There’s also speculation that she is pregnant with twins. “She’s thrilled,” a source told E! News.

Hayden Panettiere

“Nashville” star Hayden Panettiere might have said she wanted to wait until she was married to have children, but life doesn’t always work out that way. The engaged actress became pregnant with fiancé Wladimir Klitschko’s child, but according to the heavyweight boxer both of them cannot wait to be parents. He told E! News he was “looking forward to having my life change for the good.” There’s no official word on how Panettiere’s pregnancy will play into the “Nashville” storyline. 

Rachel Bilson

Former “O.C.” star Rachel Bilson and fiancé Hayden Christensen are rumored to be expecting a baby girl, her “Hart of Dixie” costar told Hollywood Life. “I haven’t bought her anything yet because I feel like it has to be super special. She’s such a fashionista, it’s gotta so be cute and so perfect for her little girl,” McKaley Miller said. The couple is reportedly expecting their bundle of joy to arrive in the fall.

Sarah Drew

The “Grey’s Anatomy” star and her husband Peter Lanfer are adding another edition to their family, her rep confirmed to Us Weekly. "Peter and I are delighted to announce our pregnancy," Drew, 33, told the news site in a statement. "We can't wait to introduce Micah to his little brother or sister." “Grey’s Anatomy” co-star Elle Pompeo reportedly gave her some advice to deal with the nausea.
