Scott Miller *has spoken out for the first time since the death of ex-wife Charlotte Dawson, saying he is "deeply shocked and saddened" by the news of her death.
In a statement released by his spokesman, the former Olympic swimmer said he was "genuinely upset" despite not having been in contact with his former spouse for quite some time, while family members are saying Miller has vowed to stay off drugs in the wake of Dawson's death.
The New Zealand-born TV presenter was found dead in her Sydney apartment on Saturday and, although an official cause of death is yet to be announced, many have speculated the 47-year-old took her life following a lengthy battle with depression.
Dawson and Miller wed in 1999 but were only together for a year before footage emerged of the athlete snorting drugs and having sex with another woman.
Despite the relationship ending more than 10 years ago, Dawson said the marriage broke her "to the core" and friends claimed Miller's recent tell-all interview with 60 Minutes may have pushed her over the edge.
Meanwhile, Dawson's "adopted daughters", who she met on the set of Australia's Next Top Model, have written tributes to their "Sydney mum" on Instagram.
Models Maddy Huett and Simone Holtznagel had to identify their mentor following her death and spoke of their sadness at Dawson's passing.
"I just want to say I won't go a day without thinking about you and remembering everything we ever laughed/cried about," Huett wrote.
Holtznagel said there was a hole in her heart and she was "trying to find solace" in the fact Dawson was where she wanted to be.
