Urban is in town to host the ARIA Awards.
Nicole Kidman's hubby will chat about his new album, Graffiti U which features his single Never Comin’ Down.
Last week, when Bickmore wrapped up her final show, she told listeners about the fears she has for her children Ollie and Evie as she prepares to welcome their little baby sibling.
"Ollie thinks we're having a boy and Evie thinks we're having a girl so one of them is going to be very disappointed and one very excited."
Tearing up on her final show the 37-year-old said, "They're so cute together."
"They're a little team. He (Ollie) never thought he was going to get a baby brother or sister and then he got a little sister and they're seven years apart and they're joined at the hip."
"And I know families of three and I know they'll all love each other so much, but I don't want anything to happen to their bond. So it makes me a little sad."
