Egg photo breaks Kylie Jenner's world record of most Instagram likes

US social media star and makeup mogul Kylie Jenner has had her world record for the most-liked image on Instagram swiped — by a photo of an ordinary brown egg.

Jenner’s birth announcement of daughter Stormi Webster on February 6 last year was the most popular post on the photo-sharing platform with 18.3 million likes but the egg, posted only 10 days ago, has already amassed 29.9 million.

“Let’s set a world record together and get the most liked post on Instagram. Beating the current world record held by Kylie Jenner (18 million)! We got this,” urged the account, named “world_record_egg.”

Jenner, 21 – the youngest of the Kardashian-Jenner clan that includes Kim Kardashian and Caitlyn Jenner – was magnanimous in her response, posting a video of her frying an egg on hot concrete.

“Take that little egg,” read the caption posted by the entrepreneur and socialite, whose net worth was estimated by Forbes magazine at $900 million, due in large part to her Kylie Cosmetics brand.

The identity of the individual behind the new record remains a mystery, although they told AFP they live in London.

“I thought it would be an interesting experiment to try and beat the record with something as basic as possible. Which led to me deciding on the egg,” they said.

“I guess it’s also a comment on celebrity culture and how fragile and easily cracked it is (pun intended).”
