Becky G opens up about secret half-sister

Singer/actress Becky G has revealed she has a half-sister she has known about since she was 13 years old.

The Power Rangers star opened up about her new family member, Amber, in a long open letter on Twitter, telling fans her sister turned 18 on Friday (29Dec17).

"For the first time, I will be opening up about something that (my siblings) Frankie, Alex, Stephanie and I, have lived with within our four walls, that I now feel ready in my heart to share with you guys, my extended family," she began.

"Today is my half sister's 18th birthday," she continued. "Yes I said it. My half sister. I learned about Amber when I was 13 years old. When Frankie was old enough and ready, my parents and I also shared this with him. Soon after that, my parents, Frankie, and I spoke to Stephanie and Alex. We all had questions and dealt with the information in different ways, but most importantly, we handled it together - as a unit."

Becky, 20, only met Amber for the first time a few months ago, but she is eager to try and build a close relationship with the teen.

"Although there has been effort on both sides to move forward in a positive direction, it takes time to catch up on 18 years and to process it all," she shared. "It's not something that happens overnight. It's all been an emotional roller coaster. The history behind it all, is something that I'd like to keep private for the sake of Amber's family and my own family's privacy."

However, Becky insists she is not ashamed of Amber: "I want you to know that I wish you all the best in life and that you find happiness wherever your heart takes you," she added. "What the future has in store for us two is unknown but I needed you (to) know this..."
