HER 'MEETINGS LOOK'
This is not the only time followers have speculated the Kylie Cosmetics founder of having "secret plastic surgery."
Kyle recently shared a snapshot of herself as she wore a stylish ensemble.
The star donned a black blazer over her white blouse and denim jeans.
She also showed off the gold and silver rings on her fingers.
Kylie hid half her face with her cell while she pouted her lips and made a kissy face.
The TV personality captioned the post: "My mom into meetings look."
Fans claimed they spotted "clear signs" of surgery as one noted: "Kylie's been clearly showing off her jawline lately, and it makes me believe she had a lower jaw implant on the corner under the ear.
Another commented: "She had a boxy-shaped lower face when she was younger. They completely widened Kylie’s face with the fillers and implants!"
KYLIE'S NEW MAN?
Meanwhile, fans have theorized Kylie has moved on from her ex-baby daddy Travis Scott, 32, since their split last year.
The mom-of-two was recently spotted in public with her rumored boyfriend Timothée Chalamet, 27.
The twosome was caught together at a family barbecue.
Kylie wore a black leather jacket, leggings, and boots at the gathering with sister Kendall, 27, and Timothée's sibling Pauline, according to the photos.
In another set of snaps, Kylie and Timothée walked side by side as they appeared to be deep in conversation in a wooded area.
The Little Women star wore a tie-dyed shirt as the makeup mogul rocked a crop top and carried a plastic cup during the lovers stroll.
Kylie shares her one-year-old son, Aire, and her five-year-old daughter, Stormi, with her ex Travis.
