Tyga Calls Kylie Jenner His ‘Fiance’ [Video]

Kylie Jenner, 18, has done her best to keep her engagement to Tyga, 25, under wraps, but did she just let the cat out of the bag with her latest social media post?

[HollywoodLife] News of their engagement was first reported on Sept. 4, when the reality star posted a selfie on Instagram in which she is clearly wearing a Cartier ring, which a source later revealed EXCLUSIVELY to HollywoodLife.com was is in fact an engagement ring!“Tyga and Kylie are engaged,” a source dished to us EXCLUSIVELY about the hot and heavy couple. “He gave her that ring and asked her to marry him. They aren’t ready to tell everyone so right now they’re keeping it a secret from most people.”

The Cartier ring in the photo was said to be a “temporary place holder” until Tyga — whose album you can buy here — gives her the real thing. And when the does happen, it’s going to be MASSIVE — maybe even bigger than Kim Kardashian’s 15-carat Lorraine Schwarz sparkler. Lucky girl!
