According to the big ole' ring on the that finger, the answer is yes. However, sources have yet to confirm whether or not the duo are engaged!
The 21-year-old had everyone talking when she stepped out in NYC last week sporting a massive sparkler.
Despite her fancy accessory, the Keeping up With the Kardashians star was otherwise dressed down. She wore a gray hoodie and jacket with jeans and minimal makeup.
If the ring is, in fact, an engagement ring, the pair has certainly moved fast. Kendall has been dating rapper A$AP Rocky for about 11 months and only first stepped out with him at the Met Gala in May.
The duo was first linked last June when they were spotted enjoying dinner together at a Paris restaurant. Since then, however, the couple have largely kept their relationship under wraps. In fact, the star has yet to post a photo with him on social media.
Only time will tell if wedding bells are in their future!
