While neither Xander nor Lauren has confirmed the relationship, Lauren has given us enough hints to basically confirm the rumor. Throughout the season, she often tweets about Xander, calling him “butterfly boy.” His nickname likely refers to the phrase he had to say at every immunity challenge to unleash the power of the idol.

And when the rumors of their relationship made it to Reddit, Lauren tweeted, “Jeff Probst works hard. Survivor Reddit works harder,” all but confirming the rumors.
