What’s that sparkly thing on Kylie Jenner‘s left hand? Apparently not an engagement ring – for now.

“Kylie has brought up marriage with Tyga to her friends lately, both jokingly and seriously,” a source told E! News. “It wouldn’t happen now but she’s been thinking about it more and wants a future with him.”

The reality star posted a photo on Instagram on Friday in which she is seen leaning into a car and sporting a huge piece of jewelry on her ring finger.

The post comes just one day after Jenner, 18, posted a photo on Facebook of herself and her on-again boyfriend Tyga, 26, with the caption, “Mr & Mrs.”

In the photo, Jenner (sans ring) sweetly rests her head against Tyga’s knee. The picture was captured at the U.S. Launch Party, which was hosted by Jenner in Los Angeles on Thursday.

Jenner has previously ignited similar rumors of an engagement to her rapper boyfriend. In July 2015, she posted a photo of her wearing a diamond band on her left hand, but tweeted soon after that she was “not planning on getting married anytime soon.”

And in December 2015, the reality star posted several photos of her hand sporting a massive diamond ring. Once again, however, Jenner shut down engagement rumors, writing on her app that although she received “an extra special gift from a special someone,” she was not engaged.

Jenner and Tyga have been dating since late 2014. Although they have split up several times since, most recently in May of this year, the pair have continually reunited shortly after breaking up.

But the source told E! the couple is “doing really well again.”

“They are super in love!” the source said. “Every time they take time apart, they come back closer than ever. It’s kind of a cycle for them but the break was good for them. It made them miss each other and appreciate each other more.”
