Jaden Smith and Kylie Jenner are only teenagers, but they are rumored to be engaged. On Instagram, Jenner, 16, posted a photo of herself with a ring on her wedding ring finger earlier this week, causing fans to immediately speculate if Smith put a ring on it.

Fans have debated for the last several months whether or not the two teenagers are even an item, as they are often seen in each other's company. Recently, photographers snapped Smith, 15, putting a gold necklace around Jenner’s neck while they were in a crystal shop.

Back in May, the two sparked controversy after Jenner posted a picture on Tumblr of herself in bed with Smith. Jaden Smith appears in the black-and-white photo half-naked while the reality TV star sits behind him. In the photo, she seems to be resting her hands on his waist as he closes his eyes and his gapes open.

Last year, the son of Will Smith and Jada Pinkett-Smith, opened up about his relationship with Kim Kardashian’s youngest half-sister.

“She's one of my best friends,” he told Wonderland magazine. "It's pretty awesome."

If the two are heading down the aisle, Jenner’s mother Kris will likely approve. "He is the greatest kid in the world," she said about the teen back in May to E!. "I'm very close to Jaden and he's like one of my own, you know?”
