"I'm going to give Imogen a baby soon," he said on-air two weeks ago. And, last month, during a discussion with his KIIS 1065 radio co-host Jackie "O" Henderson about his relaxed approach to birth control, he added: "I don't care, if a baby comes it comes."

Earlier this year, a sometimes gruff Sandilands showed off his more sensitive side when he opened up about his anguish at not being able to give his late father, Peter, grandchildren.

"I was thinking in the shower this morning ... I was regretting not being able to give him a grandchild," Sandilands said.

But while the shock jock, 45, is feeling clucky, the model and social media influencer, 26, has other ideas.

"He's got to let me ripen a little bit more. I'm still in my prime," she laughed, when speaking to Fairfax Media.

"Give me a couple of more years. I'm only 26, you know?

"We've been together for a long time, so it is due. But we are just taking our time. We are not really into rushing things. We're chilled."

When it comes to marriage for the pair, who live together on a seven acre farm in Ingleside in Northern Sydney, Anthony has the same laid-back attitude.

"Babe, when it happens, it'll happen. We talk about it, absolutely but we are just waiting. We don't need all of the titles," she said.

Asked if she has the rock already picked out just in case he gets on bended knee, she laughed, "we talk, he suggests, and that's about it".
