This afternoon Cassandra Thorburn finally opened up about her heartbreak, admitting she's grieved the loss of her husband, Karl Stefanovic since their shock split.
Meanwhile Karl sweated it out with a personal trainer at a park in Cremorne, Sydney.
Who are trying to impress, Karl?
The 42-year-old huffed and puffed his way through the work out with Bra Boy John Gannon.
Judging by how exhausted he looks, he gave it a good crack too!
During one stage Karl and the trainer took part in some boxing - and worked up a bit of a sweat during the round as the pics reveal.
Rumours of Karl splitting from Cassandra have been swirling since September when Karl was spotted on the Today Show without a wedding band.
While Cassandra has addressed the split in a roundabout way previously, today she finally opened about the depth of her emotion.
“I’m grieving the loss of my relationship. The loss of my best friend and life partner," she's said to Mum Central in the first actual interview she's given since the collapse of their 21-year marriage.
"I’m just like every other mother and wife who is going through a marriage break up."
