Isabella Leong is making her career comeback after starring in Sylvia Chang's film, Nian Nian, last year.
The 25-year-old will also star in a stage play, Sign of Happiness next month, alongside her mentor, Jim Chim.
After breaking up with Hong Kong tycoon Richard Li, Isabella had remained out of the limelight and stayed in Canada with her three sons.
She then decided to return to Hong Kong after she received positive reviews about her acting.
She, however, was jittery about her comeback.
Isabella said: "I will be lying if I say that I don't feel stressed out.
"I am nervous, but I will not back off."
Isabella had previously dated her billionaire tycoon boyfriend for two years and gave birth to three sons.
She reportedly initiated the break-up.
"If I was not given a sense of security, I might as well call it quits," she said.
She had also denied receiving a HK$500 million break-up fee from her ex-boyfriend, saying: "There was no alimony, no break-up fee. No such thing!"
She added: "Work has occupied most of my time. I will not date for the sake of dating.
"I have three boyfriends now [referring to her three sons]."
