Mystery Girl is the twenty-second album by American singer Roy Orbison. It was his last album to be recorded during his lifetime, as he completed the album in November 1988, a month before his death at the age of 52, and it was released posthumously by Virgin Records on January 31, 1989. It includes the hit singles "You Got It", which was co-written by Orbison and his Traveling Wilburys bandmates Jeff Lynne and Tom Petty, and "She's a Mystery to Me", written by Bono and The Edge. The album was a critical and commercial success; it peaked at number 5 on the Billboard 200 in the United States, the highest position Orbison had achieved on that chart, and number 2 on the UK Albums Chart.

"She's a Mystery to Me" is a song by Roy Orbison, written by Bono and the Edge of U2. It was released on Orbison's final (posthumous) album, Mystery Girl, and as the album's second single in March 1989. The song was received favorably by several music critics and is considered one of the highlights of the album.
