Seeing double! Kourtney Kardashian shows off baby bump as she transforms into sister Kim by rocking THAT viral floral dress she wore to the Met Gala in 2013 while pregnant with daughter North

Kourtney Kardashian kicked off the Halloween weekend by unveiling her epic Halloween costume, transforming into her sister Kim.

The POOSH founder, 44, showed off her baby bump in the same form-fitting floral Riccardo Tisci that Kim, 43, famously wore to the 2013 Met Gala while heavily pregnant with her daughter North West, now 10.

The SKIMS CEO’s appearance was absolutely trashed online, with many ruthlessly comparing her to the grandma-worthy sofa and Robin Williams’ character from the film Mrs. Doubtfire.

Kim, who attended the event for the first time with her then-husband Kanye West, previously confessed Fashion that she cried “all the way home” when she caught wind of the endless memes and jokes circulating about her.

In her photos shared on Friday, Kourtney looked almost identical to Kim as she donned the controversial dress and matching heels that Kim wore.

Kourtney — who is expecting her first child with husband Travis Barker, 47 — even copied the star’s exact hair and makeup, which included a statement berry lip and a sleek, low ponytail.

“Freaky Friday,” captioned by Kourtney, referencing the film of the same name that follows a mother and daughter who switch bodies after accidentally conjuring a spell.

She mimicked Kim’s poses on the red carpet, with the mother-of-four in particular placing her hand on her stomach and sticking her leg out of the dress’s dramatic slit.

Kim has yet to comment on her older sister’s costume.

Earlier this week, the Kardashian-Jenner clan gave their fans a peek at the Halloween decor at their respective mansions in Hidden Hills and Calabasas.

Kourtney did everything she could to make the most of the mega-mansion she shares with husband Travis and their children.

She had skeletons at a table and tons of candlesticks and white pumpkins set up in the hallways.

Kim recently revealed that Kourtney is on bed rest as she prepares to welcome her new baby.

The reality TV star turned 43 on Saturday and celebrated with a family celebration involving her mother Kris Jenner and sisters Khloe Kardashian, Kendall Jenner and Kylie Jenner, but mother-of-three Kourtney was noticeably absent and Kim has now explained why.

In a post on Instagram, Kim wrote: ‘So blessed to have hit the friends jackpot! I never could have imagined that I would be so lucky to call these girls my friends.

‘Thanks for all the birthday love. And Kourt, I’m jumping into your bed next week for our bed rest picnic.”

Other guests at the bash included Hailey Bieber, Sara Foster and Olivia Pierson.

Kourtney’s due date is expected to be in the coming weeks as she nears the end of her pregnancy.

She previously suffered a terrifying health crisis when she was admitted to hospital to undergo emergency surgery to save the baby’s life. No further details about her current condition have been released.

However, ‘The Kardashians’ star Kourtney did acknowledge Kim’s birthday in an Instagram post where she insisted their TV fights aren’t that bad.

In a post to her Instagram Stories, Kourtney wrote, “Happy happy birthday to my first sister @kimkardashian! “Thank you for all these years of being in charge and really listening to all my crazy ideas.”

About their most recent squabble, she added, “People think the fights they’ve seen on TV are bad… if only they could witness the hair-pulling, nail-biting fights of early high school.

‘The joys of sisterhood. I love you very much, forever and ever. May God bless this year with love, happiness and abundant joy.”
