Michael, Kyly Clarke split: She was still wearing her ring last week

Kyly Clarke put on a brave face while running errands in Sydney last week, in her last public sighting before it was revealed she had separated from husband Michael.

The Clarkes, who married in 2012, announced on Wednesday they were planning to divorce, after keeping up appearances for five months.

The 38-year-old former model was pictured outside her regular gym in Rose Bay on Monday, February 3. 

She appeared to be wearing a black band on her ring finger, which she is known to wear instead of her ring when working out.

She seemed to be in a good mood as she stepped out in the rain in skintight leggings, a Puma singlet and sneakers.

Meanwhile, Kyly's good friend, radio host Kyle Sandilands, spoke about the break-up on air on Thursday morning.

He told listeners of The Kyle and Jackie O Show he had recently bumped into Kyly in Sydney and 'something was not right there'.

At the time, it was not public knowledge that the Clarkes were living apart.

'You know when you think, "Something was not right there?" There was nothing obvious but I caught a vibe,' he said.

'I thought to myself, "God, have I said something about them [Michael and Kyly] that I should have?" Because I like them, I wouldn't say anything s**t about people I like.

'I just got a vibe, and it must have been these two going through [a separation]. Because I think I would have asked, "How's Michael? How's family life?" I would have definitely said all those things.'
