The pair, who played Summer Bay lovers Aden Jefferies and Belle Taylor, set tongues wagging at the recent Logie Awards ceremony by spending most of the night in each other's company.
Additionally, Tovey reportedly added fuel to the fire by joking that Lasance was her "husband" in a conversation with a photographer.
However, speaking to TV Week about the possibility of real-life love, Lasance insisted: "The fans would love to see that - but no, Jess and I are just really good friends. I love her, though. I think she's amazing."
The actor also revealed that he and Tovey now wear each other's rings, explaining: "We were at a party and I grabbed her ring off her and she grabbed mine off me. I said, 'I'm keeping it', and she said, 'Well, I'm keeping it, too'. We did a swapsie and it stuck. We've been wearing each other's rings for six to eight months."
Lasance quit Home and Away last year in order to pursue a Hollywood career.
