Has Kris Jenner done a Kylie and blown up her lips?

When it comes to cosmetic surgery, the Kardashians are hardly shy.

But Kris Jenner isn't about to admit that her lip doubling in size is down to a little collagen reaction. Or perhaps more aptly described as doing a Kylie Jenner.

In fact, the 59-year-old claims her huge lip is the result of a bite during a break in the Dominican Republic. Do you believe her?

The momager and reality TV star was set to star on a live segment of US show, Bachelors in Paradise but had to call and cancel at the last minute.

She says: "They [her doctor] gave me everything they could possibly give me in 12 hours. It went down a little bit, but not quite enough. I'm a little too vain, I think, to go on live TV with a huge lip."

Too vain for live TV but totally okay to appear on Keeping Up With The Kardashians, of course. Ahem.
