Missing twin Potter

The students of Hogwarts 1977 just watched the life of 1977 just finished watching the life of Harry potter 2 days ago, they are willing to change for the better. The people from the future (Golden trio, Draco, Daphne, Astoria, Blaise, Theodore and some others like the Weasley twins and most of the others who want to see their parents cause they also died when they were younger or in the war) decided to stay for a while to bond with their parents. The parents of 1977 students (which are the grandparents of the people in the golden trio era) who watched the movies are still there to know about their future grandchildren.

Suddenly, a light shone and in place left DVS just like when they were watching Harry's life. A note appeared and read it self "I am lady magic and I have decided to give you these DVD's to watch the life of Bailey Potter"

Everyone was confused especially Lily and James, they had a daughter but when they watched Harry's life, he was an only child so where was she?

Harry answered once he saw his parents' confused face "After the war I got an inheritance test, and it turns out I have a younger twin sister but she was kidnapped and taken. We have tried to find her but we couldn't"

"Wait… your sister is Bailey Potter" asked Hermione shocked, Harry nodded his head slowly confused while Hermione's face lit up and said "I know where she is, she's a famous singer and model in the muggle world oh she's my idol why didn't you tell me sooner we would've found her much earlier she's doing her tour currently and is in Germany"

Harry looked at her surprised and asked annoyed "Couldn't have said that earlier we've been looking for 2 years now" and Hermione states that Potter is actually a common name in the muggle world so she wasn't sure if they were related and even if she was sure they couldn't get close to her because of her bodyguards and she might sue them for wrongly claiming that she was related to Harry
