There鈥檚 a long-standing theory that Kate Middleton uses major hair changes to distract from pregnancy scrutiny 鈥 and her most recent appearance seems to prove that point further. At the Duchess of Cambridge鈥檚 second official outing since announcing she鈥檚 expecting her third child with husband Prince William, she debuted a shorter style.

For a children鈥檚 charity fundraiser in London on October 16, Middleton, in an Orla Kiely pink dress, black clutch, and shoes, wore center-parted locks that grazed the tops of her shoulders.

The lob could just be an optical illusion thanks to her big barrel curls of course, but it seems several inches shorter than it was for World Mental Health Day last week, during which Middleton was *shockingly* body-shamed for not looking 鈥減regnant enough.鈥

After her appearance, the official royal Instagram account posted a pic of the Duke and Duchess, which elicited some rather harsh comments about her body. 鈥淚 can鈥檛 believe she鈥檚 prego, she looks too thin,鈥 wrote one commenter. 鈥淲here鈥檚 the baby bump? Being as this is her third she should have popped sooner,鈥 wrote another.

While the short style could be a sly attempt to distract critics, Middleton, who is once again battling extreme morning sickness, didn鈥檛 seem to be terribly affected by the haters. In fact she showed just how bouncy her hair was as she took a twirl on the dance floor with Paddington Bear.

Do you think Kate Middleton cut her hair even shorter ? Let us know @BritandCo!
