Billy Magnussen and his girlfriend Erica Firestone went on the ultimate double date last month with their friends Zosia Mamet and Evan Jonigkeit.
The group of four went on a week-long getaway to Sandals Dunn’s River in Ocho Rios, Jamaica back in January 2025.
Billy, Erica, Zosia, and Evan spent their week playing golf at Sandals Upton Estate Golf & Country Club and trying out snuba, which is a combination of snorkeling and scuba diving.
A source said they also spent time at “the resort’s spa and enjoying a cocktail at the resort’s Dunn’s Rum Club, they also explored the neighboring Dunn’s River Falls, went swimming at the Blue Hole, and visited Mystic Mountain, a rainforest adventure park.”
Billy shared a video from the golf course on Instagram.
