Kourtney in labour and peckish?

Kourtney Kardashian has sparked reports she is in labour and is having a water birth.

The 33-year-old reality TV star - the elder sister of Kim and Khloe - is currently expecting her second child with boyfriend Scott Disick.

Kourtney tweeted a picture of a takeaway drink from US restaurant chain Chick-fil-A and wrote: "Chick-fil-A and a water birth. No big deal."

She is yet to respond to the floods of congratulatory messages on Twitter from fans.

Kourtney and Scott are already parents to two-year-old son Mason Dash, and it has been reported Kourtney is hoping for a daughter this time.

Meanwhile, Oprah Winfrey has conducted an interview with the whole Kardashian family, which will air on Sunday.

In a preview clip the sisters insisted they have never felt exploited by having their mother Kris Jenner act as their manager.

Kim said: "We have to hire a manager, so regardless, someone is going to get that. No one will fight harder for you than your own mother. She knows us, she knows all of our moods. We just get each other, we vibe, it works."
