"My battle with the auto-immune disease Churg-Strauss means I can't carry another baby myself," she says in the post.

"We're incredibly blessed to have my childhood friend Sophie Braggins carry our precious bundle for us, and to have the unwavering support of her husband Michael."

"Hopefully you’ve enjoyed our company, the laughs, the tears and the inspirational moments." Source: Seven Sharp

Street and husband Matt France have two daughters, Juliette (5) and Mackenzie (2).

Street co-hosted Seven Sharp along Mike Hosking, but left the role last year.

She currently hosts The Hits radio breakfast show - Sarah, Sam and Toni.
