Following a surprise birthday bash thrown by Jenner and Tyga's 4-year-old son, King Cairo, the Keeping Up With the Kardashians star treated her man to a day at a gun range in Arizona with friends (flight and all!), along with a sparkling 60-carat bracelet, as documented on her Snapchat.

The rapper later posted a photo to Instagram of his shiny new birthday present with the caption, "Vvs nothin less," referencing the near-flawless clarity of his diamonds.

Later that night, Jenner slipped into a skintight white dress with spaghetti straps and matching heels, completing her look with a sleek ponytail. The reality star posted several sexy photos to Instagram of the curve-hugging dress, following a series of even sexier, NSFW snaps posted earlier that day. "Birthday behavior," she captioned one of her and Tyga in a gentle embrace.
