‘On the tele last night and in the @katetimmarty studio RIGHT NOW!’ the actress and radio host wrote alongside three love heart emojis.
Kate was spruiking her much-loved radio show Kate, Tim and Marty on Nova 969.
Nick appeared on the ‘Quick Draw’ segment of the show before which he and Kate traded quips about underwear.
‘Did you do undies or something?’ Kate asked Nick – referring to an underwear advert he was involved in.
‘Yeah do you need some support or are you doing OK?’ Nick replied.
‘No, no, I’m fine. Jockey’s fine,’ Kate responded, referring to the underwear brand she models for. ‘You should get into them.’
Kate shared a clip of the tongue-in-cheek encounter to her Instagram page where, a day later, she paid tribute to her adorable daughter on her birthday.
‘You know the world of love and priorities have changed when you’re prepared to post a photo of you looking like a Groper in order to celebrate the most divine person you know,’ Kate wrote alongside a photo of the pair.
‘My little bestie is 4 years old today and if I’m honest she has taught me far more than I have her over that precious time.
‘I love and adore every inch of you Bubba and yours is the only unconditional love I have ever known. Free and light and one I am happy to drown in. Being four is going to be wonderful my dear girl. I promise you xx Mumma.’
