What celebrities wear during winter pregnancies:

Gwen Stefani is expecting her third child at the age of 44, and pregnancy doesn't seem to change her much. Except for a visible baby bump, the No Doubt singer/fashion designer stays true to her style in a black and white outfit, a pair of lace-up boots and red nails. Her comfortable pants were paired with a fitted t-shirt and blazer, as well as black and white spotted sunglasses (similar here).

Kelly Clarkson is at her first pregnancy, which explains why it's not so great for her. Unlike Gwen Stefani, Clarkson confessed to Ellen DeGeneres that she doesn't feel very glam: “And that’s the thing too you’re not attractive when you’re pregnant. Like everybody tells you you glow and you’re hair is pretty and you’re nails are pretty. That’s is total crap. My nails are short, my hair still falls out like it’s not all lush and beautiful and I have no glow. Unless it’s like something left over from a bad throw up. It’s horrible. I’m done talking. I’m sorry.” However, we think she did well wearing a red dress on the show, which was very much into the Christmas theme of it.

Olivia Wilde is barely pregnant, and she keeps in shape with her Pilates classes. The actress was spotted wearing jeans and flip flops, a tank top and hoodie. “Pilates is great for building core strength even as the belly gets bigger and bigger,” Harmony Studios' owner Karen Schwalbe-Jones told E! News. “Using the Pilates reformer allows for a very personalized work out allowing us to modify Olivia's session each time she comes in.”

Drew Barrymore pregnant

Drew Barrymore is wearing a comfortable striped top with jeans and flats, as she grabs some fruit drinks. She also wore simple, light brown sunglasses to go with the outfit (similar here), and a Chanel bag. Although we think she looks quite nice, the actress revealed that she's not looking to appear perfect during this time of her life: “You're not supposed to look perfect while you're making babies – making babies is the perfection,” she said.

Kate Winslet pregnant

Kate Winslet covered up in jeans,a t-shirt, scarf and winter coat, but she kept her Converse on as she showed a growing baby bump earlier this month in Chelsea. The actress already has two kids with different men (Mia, 13 and Joe, 9), and people criticized her for this. The actress defended herself, saying her kids always lived with her: “They don’t go from pillar to post; they’re not flown here and there with nannies. That’s never happened. My kids don’t go back and forth; none of this 50/50 time with the mums and dads – my children live with me; that is it. That is it,” she declared.

Other pregnant celebrities this winter include Megan Fox, Teresa Palmer, and Ginnifer Goodwin.
