Karl Stefanovic shuts down rumours that Jasmine Yarbrough is pregnant with first child

Karl Stefanovic has cleared up rumours that he and fiancée Jasmine Yarbrough are expecting their first child.

The TODAY host shut down those rumblings on Thursday, telling the Daily Telegraph: 'One hundred per cent no, she’s not pregnant!"

The 43-year-old journalist added that he and the shoe designer were "all good' and "working hard" in their respective careers.

"We’re keeping under the radar," he added.

Pregnancy rumours were ignited this week after Yarbrough uploaded an Instagram snap where she wore a floral dress with a peplum detail around her waist, leading some of her followers to speculate if a baby bump was present.

Stefanovic is already father to children Jackson, 18, Ava, 12, and River, 10, whom he shares with ex-wife Cassandra Thorburn.

Stefanovic confirmed his engagement to Yarbrough in February, telling TheFIX: "When Jasmine came into my life, I had no thoughts of new love or the future, but we are happy and grateful we found each other."

He continued, "We are yet to work out when we will get married, but probably later this year. We are both very happy."

The couple celebrated their love with an intimate commitment ceremony with family and friends in March.
