Demi Lovato discovers half-sister

London: Singer Demi Lovato discovered she has an older half-sister and recently connected with her for the first time.

The 20-year-old `Skyscraper` singer said that she reconnected with her long lost older sibling, who she only found out about this year, reported Contactmusic. "I think my fans would be excited to learn that I just got to know I have an older sister that I`ve never known my whole life. I actually have a third sister that I didn`t even know about until this year. She`s in her thirties. She`s my half-sister, but I talked to her for the first time in my life when I turned 20," Lovato said. "I asked her `Why haven`t you ever contacted me?` and she said `I never wanted you to think that I ever wanted anything from you, so I`ve just kind of been waiting to see if you wanted a relationship.` I thought that was so incredible," she added. The `X Factor` USA judge, who has two other sisters Dallas and Madison - also recently rekindled her relationship with Wilmer Valderrama for the third time. PTI
