Pregnancy apparently cost supermodel Lara Stone a job.

The 30-year-old beauty found out she was pregnant with her first child with husband David Walliams before an important modeling gig in 2012. She decided to tell those who had booked her that she was expecting, but when she arrived on the job, she found out she had been replaced.

“I was really upset at the time,” Stone told Porter magazine, per the London Evening Standard. “I hadn’t yet had my three-month scan and I felt really vulnerable about everything. I no longer had a job. That was it — I had to just stop everything that I knew; the way my life was.”

She gave birth to a baby boy in May 2013 and is getting back to work, but the transition has not necessarily been easy.

“I’ve had a few meetings because when they hear pregnancy they freak out a bit,” she told Porter, “so they need to see if I fit in their clothes. Everyone’s so nice to you all the time. And it’s like, ‘Ugh,’ you don’t have to be. It feels quite alienating because it’s like everyone’s just lying to you. Because everyone’s like, ‘You’re great!’ And you’re, ‘Well, obviously I’m not.'”

Stone spoke out about the difficulties she faced during and after pregnancy in Clean & Lean Pregnancy Guide, a book authored by her trainer, celebrity fitness guru James Duigan.

"I was in maternity jeans at nine weeks. I was bloated all over, had limp greasy hair, no energy and I could eat (and waddle) for England," she wrote. After giving birth, she had to deal with cruel comments in the tabloid about her body. "There is so much pressure these days to look fantastic during pregnancy and to lose the weight within days of leaving [the] hospital. I have nothing against hose who do, but it's not normal. Your body changes hugely during pregnancy and it takes time to go back."
