People.com Celebrity Parents Pregnancy #RealTalk: 14 Celebs Who Really Opened Up About What to Expect When You're Expecting From hormones to heels, Nikki Reed, Katherine Heigl and more tell all By Grace Gavilanes Updated on January 26, 2022 02:44 PM Share Tweet Pin Email 01 of 14 KATE HUDSON Courtesy of Harry Winston "There's all kind of differences," Hudson told PEOPLE of how her third pregnancy (she's expecting a girl!) has been unique compared to her previous ones. "They say girls make you sicker and that, for me, has been the truth. It’s been interesting so far." 02 of 14 NIKKI REED Ian Somerhalder/Instagram While husband Ian Somerhalder previously joked that he wanted to keep Reed pregnant forever, the actress grew to embrace her changing shape, admitting to Fit Pregnancy and Baby: “Being pregnant has given me this new and powerful appreciation for my body.” “Why do I suddenly have this layer of fat? Oh, it’s because my body needs to create breast milk,” she said. “Why am I hungry and thirsty? Because my body is creating amniotic fluid. I want to write my pregnant body love letters, it’s so f— cool!” 03 of 14 KATHERINE HEIGL David Livingston/Getty Images "The thing that really got me was the indigestion," the actress told PEOPLE. "You can ask my costars [on the set of Doubt], I never stopped burping. And I felt terrible about it, but there was just nothing I could do — I would be in the middle of saying something and I'd just start burping. It was awful. I felt like a frat boy." 04 of 14 AMANDA SEYFRIED Sylvain Gaboury/Givenchy Sure, the actress may have gushed about getting to meet her first child, but she admitted to having one odd pregnancy symptom: “The only thing that I can’t tolerate is body odor. Normally body odor is, ‘Uh, it’s alright.’ But I cannot tolerate it anymore. If someone has it, I have to leave. I have a hard time with that.” Seyfried added: “I can smell electricity. I swear to God I can smell the TV.” 05 of 14 MOLLY SIMS Stefanie Keenan/Getty "Here's the No. 1 thing you don't say to a hormonal girl: 'I just don't understand why you're being hormonal. I don't understand why you're being emotional,' " Sims said, citing husband Scott Stuber, while opening up about her mood swings. "I'm like, 'I am emotional because I am nine months pregnant!' So, [Scott] just doesn't say a lot. He gets really quiet and I'm like, 'Well, why aren't you saying anything?!' He's like, 'Because you're acting crazy!' " 06 of 14 CHRISSY TEIGEN Instagram "Officially harder to get into the workout clothes than it is to workout," tweeted Teigen, who's been candid about her struggle with becoming pregnant. "John and I were having trouble. We would have had kids five, six years ago if it had happened," the star said on an episode of FABLife. "But my gosh, it's been a process." 07 of 14 BROOKLYN DECKER Courtesy Brookyln Decker A far cry from her What to Expect When You're Expecting character who somehow inherited a glowing complexion and superhuman energy with her pregnancy, Decker took to Instagram to show off her skin blemishes – a direct result of pregnancy hormones, she says – which she sarcastically calls "effin awesome." 08 of 14 EVANGELINE LILLY Courtesy Evangeline Lilly Hello, baby bump – and goodbye, shoes that aren’t flats! The Ant-Man star, who debuted her growing belly at the red carpet premiere for the film, telling PEOPLE, “I feel wonderful,” but, “I have to say, high heels and doing a red carpet is starting to ache.” 09 of 14 NAYA RIVERA Courtesy Naya Rivera As a PEOPLE blogger, Rivera did plenty of kissing and telling. Getting candid about her first-time pregnancy, she said she’s “now limited to about two positions in order to not squash – as my husband puts it – ‘its roof’ or have the baby (my belly) staring him in the face. I feel like men are constantly imagining their baby winking at them when they make love to their pregnant wives, thus making sexy times more few and far between.” 10 of 14 JAIME KING Courtesy Jaime King For years, King struggled with infertility and made it a point to share her story with women who have also had trouble with conception. In a heartfelt Instagram post, King – who is now mom to two sons – opened up about having five miscarriages and undergoing five rounds of IVF and 26 IUIs within a span of eight years. She ended the post with three hashtags: “#youarenotalone,” “#ihavetobebravetosupportothers” and “#realtalkthatterrifiesus” 11 of 14 OLIVIA WILDE Steve Granitz/Wireimage With pregnancy comes a much more positive, productive outlook on life, according to Wilde, who is mother to baby Otis with fiancé Jason Sudeikis. "Pregnancy does shed away all of the bulls---. It gives you more empathy because you look at everyone and you think, 'You were a baby!'" 12 of 14 MILA KUNIS Jon Kopaloff/Filmmagic We can thank Kunis for teaching men of the world not to say "we're pregnant!" when referring to his partner's baby bump. "We can't have anything, because we've got your little love-goblin growing inside of us," she hilariously stated in a live PSA on Jimmy Kimmel Live! before welcoming baby Wyatt. "You're not pregnant, we are." 13 of 14 KIM KARDASHIAN WEST Isaac Brekken/Getty You heard it straight from the source: “Pregnant KiKi does not play!!!!” tweeted Kardashian West, who is a mom to three kids, whom she shares with husband Kanye. That’s just a sample of her candid pregnancy tweets, which even prompted Twitter to reach out to ask if her account had been hacked. Nope, “#JustPregnantKeeks.” 14 of 14 JESSICA ALBA Jason Merritt/Getty Now a mother of three, Alba admits that she felt nervous while pregnant with her first daughter, which luckily did not reignite the second time around. “With Honor, I was constantly like, ‘Is she moving? Is her heart beating?'” she told PEOPLE. “I’d worry about everything, and with this baby, I don’t have the same anxieties.”
