Barbara Palvin started "spiralling" after gaining weight during her pregnancy.

The Victoria's Secret model is expecting her first child, a baby girl, with husband Dylan Sprouse and she's grateful to have such a supportive spouse in the actor because she started to feel "weird" about the way her body has changed.

Speaking on Dylan's new Wildmen podcast, she said: "That scar came back where I was like, oh the number on the scale really going up super quick and my arms are getting bigger.

"You don't have a bump yet, but your stomach is bigger, and your pants don't fit. I started spiralling.

"This is when it's important that you have a good partner. Dylan was there reminding me every single time that we're creating life."

Barbara admitted her anxiety about her changing figure came after over 20 years working in a model and feeling constantly scrutinised about her shape.

She said: "I started when I was 13. By 17, every single time I would go into the agency, they would tell me I have to lose weight. My hips were too big. I didn't even have hips yet.

"I've been already scarred for constantly getting commented on my body. From my agency - from the industry in general to lose weight. Lose weight, be skinnier, do this, do that. I was trying to do all that. I was dieting. I was eating unhealthy. I was going crazy 'cause I would think like, 'Oh my god, I'm in such a good shape.' "

Barbara received a lift when she received a job with Victoria's Secret - but her feelings quickly changed.

She said: "I'm like, 'F*** yeah, it's working out.' And then they put the label on me that, 'Oh, she's the first plus-sized model.' "

The 32-year-old beauty insisted it isn't hurtful to be considered a plus-sized model but she didn't view herself that way and had been "torturing" herself to fit into a conventional body type.

And when she did lose weight, Barbara faced even more criticism.

She said: "I started posting pictures and then I started getting a comments, 'Oh my god, why is she so skinny?'

"I get it in a sense like, I'm a public figure, I'm a model, so I am working with my body, so that should give them the right to comment on my body.

"But I never felt the need to comment on anyone's body, or if I had nothing nice to say, I didn't say, I just kept it to myself."
