"I think he just really admires her work," Dylan explained to ET on Monday while promoting her upcoming feature film debut, The Condemned. "They're just really good friends and [I think] it's sweet that they can have this relationship."
Madonna's marriage to Sean came to a tumultuous end more than two decades ago after accusations of domestic abuse. In 2000, Madonna tied the knot with director Guy Ritchie, but they divorced less than a decade later.
Meanwhile, Sean wed Robin Wright in 1996 before they split up in 2010. Aside from Dylan, the couple also share a son, 22-year-old Hopper Jack Penn. And in May, Sean and his former fiancée, Charlize Theron, called it quits.
