The Royal Baby is due in July, but you'd never know it to look at Kate Middleton, aka the Duchess of Cambridge. Her baby bump is a barely bump, but there's no need to think she's hiding something or not eating enough. It's just genetics!

According to Us Weekly, Kate is 5'10" tall and her thin frame is something she got from her mother, Carole Middleton, who carried all three of her babies the same way. “Carole didn’t show for a long time,” a source told Us (via HollywoodLife). "She wore nonmaternity clothes right up until the final weeks. So it was no surprise to the family when Kate stayed little."

It’s funny how different bodies can be. Remember how big Gisele Bundchen got with her second baby, then — poof! — she was back to her supermodel self in no time. And Claire Danes barely ever looked pregnant the whole way through. Genes! They do their own thing.

Kate and Prince William are also on the cover of this week's People, talking about his potential work change and preparations for the baby.
