Lily Collins has announced the birth of her daughter, Tove Jane McDowell, who was born via surrogate. Collins joins a long list of celebrities who have used surrogacy to expand their families. Surrogacy can cost hundreds of thousands of dollars, with celebrities likely paying even more for special arrangements to ensure their privacy. While surrogates don't earn extra money for carrying celebrity babies, they often receive perks such as private chefs, personal trainers, and spa days. Celebrities also go to great lengths to keep their surrogacy arrangements private, using iron-clad NDAs and other measures to protect their privacy.
