demi lovato secret half sister getty Demi Lovato reveals sister she recently found out aboutDemi Lovato recently had some life-changing news — she found out about an older half-sister she never knew she had.

“The X Factor” judge was doing an interview on WBLI’s “Dana & Jeffrey in the Morning” to promote her new single, “Heart Attack,” when the host asked Lovato if there was anything she wants to talk about “before TMZ gets a hold of it.” And Lovato did, indeed, have quite the tidbit for her fans.

“I just got to know I have an older sister that I have never known in my whole life. She’s in her thirties,” says Lovato. “She’s my half-sister, but I talked to her for the very first time in my life around when I turned 20.”

“I asked her, ‘Why haven’t you ever contacted me?’ She just said, ‘Well, because I never wanted you to think that I wanted anything from you. So I’ve just kind of been waiting to see if you wanted a relationship.'” recounts Lovato.

“I thought that was so incredible. So I actually have three sisters!” Lovato says.

This new sibling joins Demi, Demi’s 25-year-old sister Dallas, and Demi’s 11-year-old half-sister Madison De La Garza.
