Jay-Jay Feeney delivered a terse response to her ex-husband Dom Harvey calling his current Edge Breakfast co-host Meghan Annear his "favourite leading lady".
Harvey wrote a lengthy post about Annear on Instagram, as part of a commitment he made this year to working on his mental health and appreciating the important people in his life.
In it, The Edge radio veteran praises Annear for her talent, quick wit and kindness, among other things.
"I strive to be a better announcer because of her. Thank you @meganonair for teaching me so much and for being my favourite leading lady in my radio career," he concluded.
Almost immediately after the post went live, Feeney chimed in with a simple "Ahem" in the comments section.
Feeney and Harvey announced their separation in 2017, after nearly two decades together and about 15 years as on-air co-hosts.
The pair have remained good friends since breaking up, and despite both having entered into new relationships, celebrated Christmas together with their families last year.
Harvey's latest Instagram post comes after a moving on-air segment in which he revealed his mental health struggles and his commitment to seeking help.
Some Instagram commenters questioned the legitimacy of his gushing post about Megan, after the Edge Breakfast Show held a social media intervention for Harvey, claiming he posted about running too much.
"Is this Meg on your Instagram?" one comment read.
"Lol I'm guessing you guys have started the intervention," said another.
