Kylie Jenner surprised her boyfriend Tyga for his 27th birthday by sharing a racy photo of the couple. “Happy birthday baby,” she captioned the image.

Jenner also shared a second photo from the same photoshoot, but in black and white. There, the couple are less serious and share a moment of laughter. “Irreplaceable,” Jenner wrote in the description of the second photo.

Tyga turned 27 on Saturday, and Jenner decided to throw him an early surprise birthday party with the help of his 4-year-old son, King Cairo. Jenner invited over a few of their friends over for the celebration, and ordered a lot of sweet treats.
