Turns out that the 28-year-old star was working on a new single titled "You're Always Here" and according to her Facebook page, part of the proceeds from the track's sales will go to the St. Judes Children's Research Hospital.
“With all the amazing stuff that’s happened this year, some moments haven’t been so amazing. I lost my grandfather exactly three months ago and it’s always hard to lose someone,” she said.
”I was inspired to start writing and it was helping me heal and I would go on walks and come home and have written stuff and Chris, who produces music, sat down and produced and we wrote this song together and that’s the song for my grandfather.”
The former High School Musical star also spoke of her relationship with fiancé Christopher French whom she calls "the guy."
"I think from the moment that him and I met, I just knew it. I was like. ‘Okay, this is the guy,’" she explained. "And he knew the same thing. It was just this feeling that it doesn’t get any better. I can’t explain it!”
