The Rolling Stones frontman, 70, arrived in L.A. Thursday on his journey to bury his longtime lover, who took her own life in New York City on Monday. She was 49.

"I am still struggling to understand how my lover and best friend could end her life in this tragic way," Jagger posted on Facebook Tuesday. "We spent many wonderful years together and had made a great life for ourselves. She had great presence and her talent was much admired, not least by me. I have been touched by the tributes that people have paid to her, and also the personal messages of support that I have received. I will never forget her."

Following the tragedy, Jagger's band The Rolling Stones canceled tour dates in Australia and New Zealand.
