Kourtney Kardashian has shut down rumours she's pregnant

In response, Kourtney insisted she is simply indulging in Italian cuisine and is still breastfeeding her 20-month-old son Rocky - whom she has with husband Travis Barker.

One user commented on the Instagram carousel she posted from the vacation: "You can tell from the bikini reflection photo Kourtney is pregnant again."

The Kardashians star - who also has Mason, 15, Penelope, 13, and 10-year-old Reign with ex-partner Scott Disick - replied: "Or breastfeeding, eating gelato, focaccia, pasta, not working out and living my best damn life baby!"

Travis is also dad to Landon, 21, Alabama, 19, and stepdaughter Atiana, 26, from his marriage to Shanna Moakler.

And, Kourtney recently said she believes their blended family has given them a "deeper" existence.

Appearing on her sister Khloe Kardashian's Khloe in Wonder Land podcast, she said: "I love my role as stepmom, because I don't feel like its up to me to discipline.

"We've kind of allowed each other to-we'll talk about it, he can handle the harder things. I definitely give advice or try to be a good role model.

"Some days I've thought like, 'Wow, this is really hard blending families.' But even in the days that are hard, there's so much more love. It's such a deeper, richer existence."
