The couple could barely keep their hands off each other as they had a late Valentines Day date in LA.
Last year, the Love Island Australia star confessed to already be thinking about marrying boyfriend Joshua Gross just five months after they met on a flight.
In fact, the only reason why the loved up pair have kept their relationship hidden for so long is because of Joshua’s previous marriage, according to the Daily Mail.
"Once they went public they hoped they could hide or try brush over the fact Joshua still legally had a wife, despite being separated when he met Sophie," the source explained.
"Joshua even deactivated and wiped his social media accounts months ago after they met including pictures from his wedding to try and keep it a bit of a secret."
Sophie and Josh’s current situation is also hindered by the fact Josh is still based in America.
"As far as we're aware Joshua is still living in America and just splitting his time."
Sophie told Nova 96.9's Fitzy & Wippa that the besotted pair immediately hit it off.
"We were talking for hours, and then I just said, 'can I kiss you?' 'cause I'm so awkward. And he goes, 'yeah!', and I went, 'could you get my toothbrush out of that little case?"
"And so he got toothpaste out and a toothbrush and we both went and brushed our teeth and then, yeah... I've been talking to him ever since."
