Then last week, new photos of the E! reality star popped up, showing that it wasn't just a trick of the camera or an overzealous Photoshopper that resulted in Kim's sudden trout pout.
And while we know Kim has been open about (to the point of documenting on TV) her previous dalliances with injectables, there's no denying that her lips certainly appear to have plumped up in recent weeks. So, has Kim picked up where Lisa Rinna left off? Did she get lip injections? Put your plastic surgeons on hold, this rumor is…
If there's one area Kim doesn't need help in, it's the beauty stakes, and while she acknowledges that she's been looking a little puffy in the mouth region lately, she assures us there's a perfectly good syringe-free explanation for it.
"I absolutely did not get lip injections," she told E! News. "That's ridiculous. I've always been pretty open and honest and have no problem admitting that if that was the case—but it's not."
So what's the deal? Just a little thing called the common cold.
"I had the flu and that pic was taken right when I woke up with no make-up," she said of the paparazzi shots. "To be honest, it doesn't even look different, but if anything, my bottom lip looks bigger, why would I do one lip?"
So there you go: our girl Kim is 100 percent natural. Which might be something of a burgeoning trend.
After years of speculation on the worst-kept secret in Hollywood, Nicole Kidman has finally come clean about her own familiarity with face plumpers, admitting that she used to get (are you sitting down for this?) Botox. Not exactly a bombshell revelation, given the curiousness of her previously immobile forehead.
Kidman reportedly made the revelation to a mystery German magazine (who can keep track of things like titles?) while promoting Rabbit Hole abroad.
"I've tried a lot of things, but apart from working out and a good diet, most things don't help," she said. "I even tried Botox, but I didn't like how my face looked afterwards. Now I don't use it anymore—and I can move my forehead again."
Hooray! Nothing like starting the new year off with a little honesty.
