Kylie Jenner tweets to quell baby rumors: "CLEARLY I'm not pregnant!"

Kylie Jenner will not be the next new face on "Teen Mom."

The youngest member of the Kardashian-Jenner clan, 17, shot down eight months of pregnancy rumors in a single tweet in response to speculation that she was carrying 25-year-old rapper Tyga's baby.

"People been thinking I'm pregnant for 8 months now... CLEARLY I'm not pregnant!" the 17-year-old tweeted Wednesday.She followed up her statement with physical evidence of looking tiny-waisted in a jumpsuit.

This is not the first time Jenner took to social media to address claims of becoming a teen mom, although she has yet to speak publicly about her alleged relationship with Tyga. Back in December she was already striking back at widespread suspicion when she admitted to gaining some weight. "[I'm] not trying to become a rapper, I'm not getting married, & I'm not pregnant ... " Jenner tweeted at the time.

Baby rumors had hit a pitch in March when Jenner posted paparazzi photo of her pumping gas on Instagram, with the inscription "throwback to when I was 15 pounds skinnier & had a little blonde goin on," prompting pregnancy-theorists to claim it was baby weight.
