The Grammy-award winning singer, 38, was pictured with her two children, 15-month-old Jameson Moon and Willow Sage, 6, in an issue re-named "The Beautiful Issue," which included Meghan Markle among more than 70 other female celebrities, and five men.
It features "beautiful women (and a few men) of all shapes, sizes and colors, and celebrates the most beautiful qualities of all: strength, humanity and artistry," Cagle added.
Pink, known for her acrobatic live performances, has scored hits like "What About Us" and "Raise Your Glass" over a 20-year career.
The Beautiful Issue hits U.S. newstands on Friday.
