That's the latest buzz about Demi, who revealed news that she has a half-sister she never knew about until recently.
During an interview with WBLI radio station, she was asked if there was something about her that her fans don't know: "I just got to know..I have an older sister that I've never known my whole life. She's in her 30s. She's my half-sister. I talked to her for the very first time in my life around when I turned 20."
So, why did it take so long for her sister to make contact with Demi?
Demi explained, "I asked her, 'Why haven't you ever contacted me?' She said 'Well, because I never wanted you to think that I wanted anything from you. So I've just been waiting to see if you wanted a relationship.'"
Demi added, "I thought that was so incredible. So, I actually have a third sister, that I didn't know until this year."
She definitely isn't one to keep secrets, though there is one area Demi won't comment on--who she's dating.
When asked about hanging with Wilmer Valderrama, she said, "I actually like to keep my private life, love life and stuff like that ... I like to keep it very sacred. There are some things you just have to keep to yourself. Unfortunately, no I would not like to comment."
