Jane, 24, and RK, 33, have been rumored to be romantically involved since they were paired onscreen for the first time via the 2018 teleserye Araw Gabi.

In February, the two fueled speculation that they're dating after they posted on Instagram photos suggesting they went to Lake Caliraya in Laguna together.

It can be recalled that a year prior, Jane was tagged as the supposed third party when RK broke up with his longtime non-showbiz girlfriend, a rumor that the actor denied in an interview with Boy Abunda.

“As far as I’m concerned, walang third party. We care about each other so much. Nag-usap kami nang maayos. We just couldn’t bring it back to what it used to be,” RK said of his ex-girlfriend at the time.

Meanwhile, in a separate interview that same month, Jane denied being officially together with RK. However, when asked of the possibility that they could become a couple, the actress said: "Wala naman akong isinasara. Hindi ko naman pinipigilan at wala rin akong hinahanap. Kung darating ay darating."
