German supermodel Heidi Klum, who is pregnant with her fourth child, has banned her three kids from jumping on her stomach any more.

The 36-year-old model is due for delivery in October and she had to take strict action as she feared that the children could harm their unborn sister with their playfulness, reports contactmusic.com.

"I had to stop them jumping on my tummy. They don't really understand there is actually a real human being in there," Klum has been quoted as saying.
