AceShowbiz - Kylie Jenner is known for her aesthetic Instagram feed. In her recent post on the photo-sharing app, however, the Khy founder sparked concern among fans as they spotted a dangerous detail in it.

In the said post, Kylie treated her almost 400 million followers to a series of photos and a video taken while she was onboard a yacht during her birthday vacay in the Bahamas. The Kylie Cosmetics founder was seen leaning on the yacht's metal railing as the "mother storm" was raging behind her.

While the photos and a video were visually pleasing, some of the reality TV star's followers pointed out a safety issue in the post. "Holding on to a metal railing during a lightning storm is crazy," one noted in the comments section.

"Sis, don't grab the railing," another similarly wrote. One other fan asked, "Love, please be careful."

According to Boating Safety magazine, Kylie's stunt could have put her in a dangerous situation as she could be electrocuted. "That can be a deadly spot to be if there's a strike," the article says of metal objects. "Boating can be an enjoyable and thrilling experience, but getting caught in a severe storm on the water can quickly turn a pleasant day into a dangerous situation."

While Kylie hasn't responded to fans' concern, "The Kardashians" star allegedly had a total blast celebrating her 27th birthday along with boyfriend Timothee Chalamet and a group of friends in the Bahamas on August 10. "It was a nice break for her," said a source to PEOPLE.

The insider claimed that the mom of two is "incredibly happy with him. She's never been in love like this before." The "Call Me by Your Name" star is allegedly "great for her."

The informant continued, "Her family loves him. He's so discreet and always has her back. He's very much a gentleman and everything that Kylie deserves. They are very serious."
