But worrying new photos have emerged showing the actress looking distraught and shaken.
In pictures exclusively obtained by New Idea, Lynne - who plays Irene Roberts on the long-running Channel 7 staple - can be seen breaking down to co-star Emily Symons on set at Sydney's Palm Beach.
The scenes, which were filmed on February 19, look set to make for dramatic viewing with the TV star holding her head in her hand and showing visible distress etched across her face.

Lynne has played the character of Irene for almost 26 years, and last year revealed she has no plans to quit any time soon.
The 66-year-old told News.com.au: "As long as I have the energy, fitness, memory and enthusiasm, and the love for it, I'll stay as long as they'll have me."
In June 2018, the age-defying actress revealed she had got a second tattoo at the age of 65.
