“I dressed up as Bad Sandy for Halloween in 5th grade and thought I was everything. Years later, THE Olivia Newton-John walked out onto my stage in Melbourne, Australia and we sang our hearts out together to ‘Hopelessly Devoted to You.’ This is a moment I will never ever forget,'” Carey, 54, said in the press release.

Meanwhile, Lattanzi said that she always knew she wanted to sing with her mom.

“After my mom played the song for me, I knew I wanted to record it, not only because it was with my mom but I felt the lyrics and message might help people see things from another perspective,” Lattanzi said. “We are all part of the same human race and if we listen to each other, respect each other and love each other — for both our likenesses and our differences — we might just understand each other a lot more.”

Just the Two of Us — the Duets Collection Volume Oneis out now.
