Kylie Jenner posted a rare photo of herself with Tyga's son, King Cairo Stevenson, on Wednesday.

The 19-year-old "Keeping Up with the Kardashians" star shared the picture on Snapchat while spending quality time with the 3-year-old and the 26-year-old rapper at home.

Jenner, who wore a pink shirt emblazoned with "Kylie" and "Tyga," gave a smile in the photo as King cozied up to her side.

She followed up with a picture of Tyga giving her a piggyback ride.

Tyga shares his son with ex-fiancee Blac Chyna, who is engaged to and expecting with Jenner's half-brother Rob Kardashian.

Jenner recently said in a Snapchat Q&A that she hopes to have children of her own someday.

"I'm getting a lot of questions about kids -- how many kids do I want, do I want kids. I do want kids, but not now," she told her followers.

Jenner and Tyga are longtime friends who went public with their relationship at the reality star's 18th birthday party in August 2015.

Jenner told Complex magazine in an interview published this week that she and Tyga are inseparable.

"The first year we started hanging out, everyone around him told him not to be with me. I still get comments like, 'Don't be with him.' But we're not doing it for the public -- we love each other," she asserted.

"We need to be together at all times," the star admitted.

"We never get mad at each other, we just figure things out."
