Earlier this month, the 29-year-old star confirmed the news that she was expecting her first child with Jason Statham on Instagram, posting a picture of herself sitting on a beach in a bikini, along with the caption: "Very happy to share that Jason and I are expecting!! Lots of love Rosie x Photo by@jasonstatham"

Rosie and the Transporter star have been together since 2010, and confirmed their engagement last year.

She went on to spark rumours that a big announcement was on the way from the pair in the New Year, when she posted the cryptic message on Instagram: "Here's to fresh starts and exciting prospects for the new year. Wishing everyone a happy and healthy 2017."

The Mad Max star also told Sunday Times' Style magazine that she was looking forward to motherhood in the future, saying: "I look forward to the many things that come with being a woman, having children, motherhood, all of that.

And on 49-year-old partner Jason, she added: "I think the longer you are together, the more you look out for one another, the more you become invested in each other's lives...

"And we really are a team, we are deeply connected. We are best mates and it's a beautiful thing. I feel truly lucky. He's a warm spirit."
