Chrissy Teigen immediately thought about the ways this might have impacted her. Everything from her codependent behavior in relationships to her struggles with addiction could be explained by the loss of a twin. "At this point, I'm making excuses for my whole life," Teigen said on Instagram. "I've always felt something missing." Unfortunately, the test results were incorrect: Teigen did not have a twin sister.

Her family confirmed this, though Teigen was hesitant to believe them. She started off with a phone call to her father asking if was in the delivery room when she was born and if he saw her alleged twin. "He starts laughing and saying, 'No, I was there. There were not two of you.' I'm like, 'Are you sure you were there?'" she continued in her Instagram post.

The puzzling results and her father's answer that contradicted it left Teigen confused. She turned to her older sister to try to sort things out and find the truth of her past.
