It was third time lucky for Roxy Jacenko when she took to the stage for her In Conversation With... business seminar on Friday alongside Seven's Sally Obermeder as emcee.

Sydney's "PR Queen" managed to avoid any mishaps this time around, after she discharged herself from hospital on her first outing in July 2015 because of an infected rhinoplasty, while coincidently on the same day as her second seminar in June 2016, her husband Oliver Curtis' sentencing hearing was held for conspiracy to commit insider trading.

Reminiscing about that day, she said: "I slipped into a sombre dress [after I held the talk] and off I went to court, you can never think life is too hard."

On previous occasions she opened up about her curious, almost soap-like private life, but this time Jacenko mostly stuck to the script, save for a few glimmers into her private life.

She touched on speculation surrounding her marriage, joking that she wished she had got Justin Bieber's number when he recently dined at Chargrill Charlie's, which is one of her clients.

"I do have some available time as you may have read," she laughed.

Checking her emails intermittently, Jacenko also discussed her decision to forgo a social life so she can focus on her businesses and her children, Pixie, 5, and Hunter, 2.

"I don't like to go out, I only network with Pixie and Hunter," she said.

After surviving breast cancer last year, she said her outlet is the gym three times a week. "Nothing feels as good as being skinny," she laughed again.

More than 600 people were in attendance at The Westin, Sydney, to hear the Sweaty Betty boss's tips and tricks on how to run a successful PR empire, with one lucky guest going home with a $13,800 3.13 carat Nicholas Haywood diamond ring.
