Scott was found dead in her apartment Monday in an apparent suicide, and police do not suspect foul play. Jagger said that he was "completely shocked and devastated" by her death.
The band’s concert in Perth on Wednesday will not be taking place. The Stones have five other dates scheduled in Australia with the next one set to take place March 22 in Adelaide.
Jagger’s spokeswoman, Victoria Scarfone, said that the rumor that Scott and the Stones’ singer had broken up was completely false.
"The story in the New York Post re: a split between Mick Jagger and L'Wren Scott is 100% untrue," Scarfone told BBC. "There is absolutely no basis in fact to this story. It is a horrible and inaccurate piece of gossip during this very tragic time for Mick."
Vogue editor Anna Wintour was a fan of Scott’s design work.
"[She was] a total perfectionist... always unbelievably generous, gracious, kind and so much fun,” Wintour said. "Her old world American manners and charm were from another time, but her sensibility was always fiercely modern."
