Lena Dunham discussed her relationship with ex Jack Antonoff at length in her newly released memoir, Famesick. "The best medicine was Jack. Here was this boy - no, at 28, he was a man," Dunham, 39, wrote. "He had strong arms, and good instincts, and models on video shoots who slipped him their numbers on napkins." Dunham added, "I didn't realize it then, but as our relationship deepened, I relied on him for more than companionship and affection.
