The E! star was spotted on Tuesday, Oct. 29, wearing a familiar article of clothing previously worn by her 15-year-old pal while shopping with some girlfriends in Los Angeles.
The 16-year-old brunette beauty paired the red Bear River Casino sweatshirt with a gray shirt, black leggings and short black boots during her outing.
The Karate Kid star sported the hoodie with a black T-shirt, while Kylie looked chic in a black patterned mini-skirt, white blouse and black leather jacket.
In March, rumors began swirling that Kylie and Jaden were an item after being spotted out together numerous times. However, the young celebs each spoke out against the claims and reassured fans that they're just really good friends.
"She's one of my best friends. It's pretty awesome," Smith told Britain's Wonderland magazine.
Meanwhile, Jenner explained to E! News at the time that her friendship with Jaden is "refreshing," adding that, "Some people don't understand and some people do. And it's just great to have someone grow up in the same position as you and you can relate in that kind of way, so it's fun."
