"I'm very lucky because he is so accepting of the mess and the chaos. He never says anything about it," she said. "He kind of thinks it’s like, charming. So I'm very lucky for that."
Waterhouse, who was celibate for six months before meeting Pattinson, said she feels comfortable building a home with the movie star after all these years because she's finally found someone who gets her, who completely understands her and can even be "comfortable" with her busy schedule.
As for why it took her so long to finally be ready to share a home with Pattinson, the singer-actress said she had to be absolutely certain before sharing her sanctuary.
"I always think the home is the sanctuary and that's why you leave everything outside," she said. "When that home center is secured, that's the most wonderful thing and that's the most important thing to me."
