The 25-year-old, who played Aden Jefferies on the Summer Bay soap, confirmed the new relationship but refused to disclose the identity of the woman in question.
Speaking to TV Week, Lasance explained: "There may be a romance. It's early days. There is a special someone there but, as always, I'm completely focused on my work. So there'll be no ring on the finger for a while!"
Vowing to take the relationship slowly, he continued: "Since I started on Home and Away, all my focus has been on my work and I don't get much time away from it. That's the issue.
"I'm not going to throw myself into a relationship and [then] not be able to put much time into it. It'd be stupid to be involved with someone when you can't really be there."
Lasance is currently working on a film spinoff of the crime TV series Underbelly.
