Kourtney Kardashian has dismissed rumours that she has given birth.

The TV star is expecting her second child with her partner Scott Disick, with the couple's daughter due at the end of the month.

The 33-year-old posted a cryptic message about a water birth on Twitter recently, leading to intense speculation she had become a mother again.

The star has now revealed what she actually meant. "Witnessed a water birth last night with @KhloeKardashian. What an experience! All I can say is WOW (sic)!" she wrote.

Previously, Kourtney had tweeted about visiting a popular take-away restaurant and "a water birth".

Her sister Kim Kardashian later told her followers on the site that she was attended a photoshoot with Kourtney and their other sister Khlo, leading many to suspect Kourtney hadn't given birth.

Although Kim was excited about the shoot for the girls' new make-up line, she was finding it hard to get out of bed.

"5:30am call time is a little early buuuuut I will wake up soon! (sic)" she wrote.

Khlo soon replied: "Just say "I know I can (sic)!"
