Pregnant Kate Upton squeezed in one more sexy lingerie shoot before she began showing, in a stunning campaign for Yamamay’s fall-winter 2018 lingerie campaign. But it wasn’t easy, she reveals on social media.

Upton says she was in her first trimester while shooting the Yamamay campaign and struggling with morning sickness.

“I was so sick in my first trimester and it was really hard to get through this shoot,” she wrote on Instagram. But I am so grateful I had a such a great team around me and now I have a new reason to appreciate my body.”

Upton married Houston Astros pitcher Justin Verlander last November, less than a month after the Astros, behind Verlander’s rocket arm, clinched the World Series.

“I got to marry my best friend,” she told Maxim magazine, after she landed at No. 1 on their annual hot list. “He’s an amazing man. He’s so supportive and focused and motivated, and he inspires me every day. I’m so very lucky that he’s my husband.”

For his part, Verlander says Upton saved his life when he was going through a dark period.

“She was instrumental in me not… like, jumping off a bridge,” Verlander, 35, told Bleacher Report. “I was depressed and kind of just upset at the world and trying to hide my own shit.”

The couple announced Upton’s pregnancy in July in an Instagram post.

For her Yamamay shoot, Upton was photographed by Giampaolo Sgura in lacy bras, bodysuits with sheer paneling and slip dresses.
