Kylie Jenner has been on birth control while reportedly dating rapper Tyga.

In the teaser clip for the second half of the E! reality series' 10th season, the 17-year-old is seen talking to older half-sister Khloé Kardashian about her contraceptives.

When matriarch Kris Jenner walks in, Kardashian nonchalantly explained, "We just switched Kylie's birth control pills."

A concerned Kris naively asked Kylie, "Do you take it for your skin?"

As her response, the teen gives her mom a glare, which hints that she is not taking the medicine for her skin.

Kardashian then jumped into the awkward moment, joking, "What do you think she does all day, knit sweaters?"

Meanwhile, Kylie recently denied being pregnant with T-Raww's baby once again.

According to HeatWorld, older sister Kendall Jenner seemingly confirmed the teenager's pregnancy claims, taking to her Twitter account on Feb. 18.

The model supposedly tweeted a snapshot of a positive pregnancy test with a message congratulating the "Ayo" rapper on becoming a father: "I don't care what anyone says. Congrats @tyga."

The publication also claimed Kendall's post was "only up for a nanosecond before being swiftly removed."

Ever since then, its screenshot has been making rounds online.

However, Kylie shot down the recent speculations with a couple of tweets on May 28, insisting that she is "clearly" not expecting a baby.

This is certainly not the first time the "Keeping Up with the Kardashians" star is dealing with the rumors that she is pregnant with the "Rack City" hitmaker's child. In December, she also took to Twitter to deny the rumors.
