"I'm going to be a dad," Baskauskas tells the magazine. "My fiancée is 12 weeks pregnant! Obviously, that's a lot more important than winning Survivor."
The news comes less than two weeks after Baskauskas proposed to Petersen.
Baskauskas won Survivor: Panama and was competing with his brother Vytas in Survivor: Blood vs. Water. Peterson is a model and clothing designer, and Baskauskas moonlights as a musician who goes by the name Odd Us.
