The Ex On The Beach star is famous for her trailing, Rapunzel-esque tresses and often pays Easilocks' Shane O'Sullivan a visit to maintain the lustrous lengths, but she decided to lop the lot off on Monday (25 July), sending social media into meltdown.
WARNING: This snap is likely to induce mane envy.
Megan took to Instagram (where else, eh?) to unveil her much shorter barnet courtesy of hairstylist pal Beau Babbington in Essex - and even though she's a ha-uge fan of sky-high Louboutins and figure-hugging pencil skirts - we've never seen her look so perfectly polished and sophisticated.
It's a thumbs up from us!
Megan captioned her snap (which racked up 23.1K likes in just under one hour), "New hair b*****s! I am in LOVE with my new look," and it wasn't long before her fans and followers bombarded the post with comments.
"Oh my god, your hair looks so much better short! Absolutely flawless," wrote on Insta-user, while another tagged a friend and said, "How beauty is her hair?!"
In fact, it was hard to find a single person who didn't rate Ms. McKenna's locks - and rightly so - it's gorgeous!
Megan - who caused a bit of a stir in Sunday's (24 July) episode of The Only Way Is Essex - isn't the only celeb to unveil a sparkling new look, though, as Big Brother's Lateysha Grace just went bright pink over the weekend and Love Island's Hannah Elizabeth braved the scissors, too!
If that isn't hair inspiration enough, we don't know what is. To the salon!
