According to an Aussie publication, the pair have been "enjoying clandestine meet-ups for the last four months."
They apparently even enjoyed a romantic date in Byron Bay last December! You can see more photos of the pair hanging out here.
An eyewitness told the publication that, "Even though they were doing their best to fly under the radar, at one point Martha got up and sat on Sam's lap. They were being really affectionate with one another."
Aside from these reports, Martha and her MAFS husband Michael are... going strong?
"They are truly one of the show's success stories and they're really in love," a source told New Idea.
Eeeek!
Back in February, Sam admitted that Martha is a "beautiful person."
"She's quite happy in her relationship, and I wouldn't want to intrude on that," he said. "I thought a couple of the girls looked good, but I would never intrude on anyone, especially Michael and Martha's relationship."
We mean, who knows anymore?
