Britain’s slim Duchess Catherine sometimes forgets she’s pregnant

Catherine, the Duchess of Cambridge, sometimes forgets she’s pregnant.

No, really. And maybe that’s why she hasn’t been favoring maternity clothes either.

The wife of Prince William, the second heir to the British throne, visited Margate’s Turner Contemporary gallery on Wednesday and told an observer that, yeah, she occasionally forgets she’s carrying a little royal.

“I said, ‘You’re looking very trim,’ ” Margate resident Jenny Cranstone told reporters after speaking with the duchess (via Hello). “She said, ‘I sometimes forget I’m pregnant.’ ”

Fear not, Kate, an entire globe of royal watchers will happily remind you that you are indeed with child.

The former Kate Middleton, who is expecting her second child next month, visited the “Self: Image and Identity” exhibition on Wednesday and viewed works by British landscape artist J.M.W. Turner — the subject of the 2014 Oscar-nominated biopic “Mr. Turner.”

Catherine has opted for several non-maternity looks during her pregnancy, as she did when she was carrying Prince George back in 2013. On Wednesday, she recycled a statement-making Hobbs Dalmatian-print coat from her first pregnancy.

The royals fueled speculation that royal baby No. 2 would be a little girl when the duchess stepped out on Monday wearing a soft pink Alexander McQueen coat and matching Jane Taylor fascinator at the Commonwealth Observance Service at Westminster Abbey.

While the color choice may not mean much, royal odds-makers took it as a sign that a little princess was gestating. The notion was further supported when she was seen shopping and drawn to girls’ baby clothes, People reported.

But, come on, who isn’t a little bit taken by the cuteness built into those miniature outfits?
