Kylie Jenner sparked even more engagement rumors after flashing giant bling on her ring finger.

The 18-year-old Keeping Up with the Kardashians star shared a pic of herself posing through a car window while wearing a baggy white "Pablo" sweatshirt, reflective round sunglasses, and -- most importantly -- a sparkling ring on her left hand.

The photo, shared to Instagram on Friday, gained 1.6 million likes and fueled talk of an engagement to her on-again boyfriend, Tyga

That ring didn't mean a thing, apparently, as a source told ET that the pair aren't heading down the aisle. “No, they’re not engaged,” the source said.

The ring fiasco is the latest in a series of moves that the reality star has recently made, hinting that she and Tyga, 26, have gotten very serious again after their most recent big split.

Last week, the Kylie Lip Kit creator posted a photo on Facebook, showing her leaning against the "Rack City" rapper. Jenner captioned the pic, “Mr & Mrs.”
