Kim Kardashian has confirmed her third baby with rapper husband Kanye West is on the way.

The reality TV star, 36, tweeted a promotional clip from the new season of her family show, Keeping Up With The Kardashians.

Speaking to her sister Khloe Kardashian, she asks: “What happens every time I say, ‘Guess what?'”

“You’re pregnant or the person’s pregnant?” Khloe asks. Kim – who has two children, North, four and Saint, 21 months – confirms: “We’re having a baby!”

Kardashian did not address surrogacy in the clip but has previously talked about pursuing it, over health issues, on her TV show.

“I didn’t think it was that realistic of an option, and now I feel like that’s my reality. I feel like surrogacy really is the only other option for me,” she has said.
