Taylor Swift, My Twin Sister

Taylor Swift has a twin sister named Nikki Swift. They doesn't know each other because they got seperated when they were still a baby. Their mother, Andrea, gave Nikki to her friend, Anna, because she can't handle them both at the same time. Now, Taylor and Nikki will have their 24th birthday and Andrea wants Nikki to celebrate her birthday with them and live with them, too. Who will Nikki choose; Anna, who took care of her for 23 years? Or Andrea, her real mother?
