Kylie Jenner addressed her apparent weight gain so Internet trolls don’t have to. The “Keeping Up With the Kardashians” reality star took to Instagram to share a new picture Friday that showed her bare hips and legs after she had donned a black body suit, while makeup artist and friend Joyce Bonelli worked her magic.

"Behind the scenes. (yes I gained weight there I said it so u don't have too) :),” the 17-year-old wrote in a caption for the image. She seemed to have changed her mind about her new voluptuous look, because the post was later edited to read only “Behind the scenes,” E! News noted. More than 1.2 million of her 23.4 million followers liked the image. It also inspired more than 50,000 comments.

Jenner strutted her curvaceous figure down the red carpet at the 2015 Billboard Music Awards, where she wore a Balmain ensemble. "I'm here!!!" she captioned one Instagram picture from the red carpet at the MGM Grand in Las Vegas Sunday. She smiled from ear to ear and lifted her arms in the photo.

But her happiness didn't last long. Things went awry when she and sister Kendall, 19, introduced brother-in-law Kanye West's performance on the show. The sisters were booed when they began to speak, and Kendall seemed thrown off by the naysayers as she looked around the stage.

The person who actually took the boos the hardest was Kylie, an insider told Hollywood Life. "Kendall didn’t really care, but Kylie seemed pretty bothered by it backstage,” the insider said. “But Kendall eased Kylie’s thoughts and told her that there’s nothing they can do about it, so stressing over it would be a waste of time.”

One less thing Jenner might have to worry about is Blac Chyna, her boyfriend’s ex-girlfriend. The two have engaged in a passive-aggressive social media feud for months, but Chyna tweeted over the weekend that she was “done with the drama” and had forgiven Tyga. The rapper didn’t respond, and Jenner didn’t respond to his scorned ex-girlfriend either.
