Editor's note: We would argue that a Hello Kitty Valentine's wallpaper collection is a bit repetitive because Hello Kitty herself is a perpetual Valentine, no matter what the date on the calendar. Over-the-top cute and oozing love and affection, she would be the perfect Valentine mascot even if you dressed her in black. But here she is in all her pink-and-red glory, ready to help you celebrate the loviest day of the year. Happy Valentine's!
