Now here's a rumor that's been trailing Kim Kardashian for years.
Fascination with the E! star's behind has always had people chattering about whether or not that famous posterior is all natural—or if Kim has had a little help in the shaping department.
And with her post-baby body on display pretty much every day, thanks to the ever-obliging paparazzi, Kim has been forced once again to shoot down the rear-end rumors.
"I'm seeing all these nonsense tabloids claiming I have butt implants-injections," Kim began a lengthy Twitter post this afternoon. "Get a life!"
She continued: "Using pics of me 15lbs skinnier (before I had my baby) comparing me to now! I still have weight to lose. Anyone who has had a baby knows how hard it is to lose weight (especially the last bit of weight) & your body totally changes!
"Making fun of me pregnant & making fun of me trying to lose weight now shame on you. I'm not perfect but I will never conform to your skinny standards sorry! Not me. And BTW I've lost a lot so far & I'm proud of that! Don't give young girls a complex!"
This is hardly the first time that Kim has had butt-implant rumors to sit on: She went so far as to have her bum X-rayed during an episode of Keeping Up With the Kardashians several years ago.
And what do you know, all natural!
Kim has been showing off her increasingly slim bod ever since dropping 50 pounds of baby weight and posting her selfie-seen-round-the-world—a swimsuit shot that bared a healthy portion of her healthy butt—which she later called "a big middle finger" to the haters who were so quick to judge.
She told E! News in December, after her first post-baby bikini pics were published, that she still had "about 10 pounds to go" before she'd be satisfied.
Kim also provided quite the rear view in tight beige pants last week, her signature curves handily telling the jerks out there to kiss off.
