Kourtney Kardashian has taken to Instagram sharing new photos of her growing baby bump.

At the weekend, the reality star and Poosh founder revealed she's expecting her fourth child and her first with husband Travis Barker at a Blink-182 concert.

Barker was playing the drums when he saw his wife holding up a sign in the crowd that read: 'Travis I'm pregnant.'

Now, Kardashian says she's "overwhelmed with gratitude and joy for God's blessing and plan" as she poses with Barker, who playfully has his drumsticks near her belly in one shot; in another, he kisses her baby bump.

The couple's pregnancy news comes shortly after the star announced in May they had given up IVF treatment in a confessional on The Kardashians.

"We would love a baby more than anything, but I really believe in what God has in store for us. If that's a baby, I believe it will happen," she said.
