Kris Jenner's bikini photo branded ‘ridiculous’ as fans accuse star of editing her figure

Kris Jenner had fans doing a double take at her recent Instagram upload.

The Kardashian-Jenner matriarch, 68, took to Instagram on Monday to pay a sweet tribute to her longtime friend Shelli Azoff, by sharing a slew of snaps to mark her birthday.

Kris uploaded a series of pics of her and Shelli showcasing their wholesome friendship that spans over four decades.

Captioning the shots, the Hulu reality star gushed: "Happy Birthday to my amazing BFF Shelli! @shellibird1.

"We’ve shared so many incredible memories over the last four decades, and I’m so grateful for your friendship and the love, laughter, joy, support, fun, and the endless surprises you have brought to my life.

"We are so blessed to have been through so much together!! You are the most amazing mother, grandmother, friend, wife, sister, auntie, and one of the funniest, smartest and most generous people I’ve ever known," she went on.

"You’ve been there through everything, and I can’t imagine life without you. Thank you for being by my side all of these years.

"I cherish you and love you more than you know!! Here’s to many more adventures and beautiful moments together! #BestiesForever #HappyBirthdayShelli," Kris concluded her sweet message.

The post included several throwback snaps of her and Shelli from their younger years, as well as more recent shots at glamorous events, and photos alongside Kris' daughters Kim Kardashian and Kylie Jenner.

However, it didn't take eagle-eyed fans long to spot a possible editing blunder on one of the pictures, in which Kris flaunted her ample cleavage and impressive bikini body in a tropical location somewhere.

Taking to Reddit, user @Oldsoldierbear pointed out: "Looks more like a big backside than breasts," referring to Kris' rather perky cleavage.

As @Itchy_Association_52 agreed, adding: "I just said outloud to myself, That's...a butt'," with @er1026 claiming: "This photo is fake in every way. Nothing about it is real. It’s a poor photoshop job."

A fourth fan @Ok-Hornet3964 admitted: "Why is this lowkey scaring me??? and @Tacosconsalsaylimon replied: "Because it's so uncanny!!! No one's chest looks like that over 55, let alone 68."

And @catsandnaps1028 chimed in: "No way her neck and decolletage looks like that at her age. Aging is fine Kris. . The Photoshop is what people will find ridiculous."
