WATCH: Rob Lowe Reveals Favorite David Bowie Song, Celebrities Remember Rock Icon

Hollywood is in mourning.

Rob Lowe paid tribute to music icon David Bowie as he left a Golden Globes after party following the singer’s passing on the same night as the awards show. “I was a big fan of his,” he told TMZ. “I’d seen him here and there. I had had a few good talks with him over the years. He was a legend. [His passing is] really really sad.” Lowe reveals his favorite Bowie song in the video above, but confesses earnestly, “There’s a billion of them.”

Bowie passed away at age 69 on Jan. 10, 2016 after battling with cancer for over year. “David Bowie died peacefully today surrounded by his family after a courageous 18 month battle with cancer,” read an official statement from his website. “While many of you will share in this loss, we ask that you respect the family’s privacy during their time of grief.”

Lowe is among the many celebrities grieving over the loss of an American pop icon. View their reactions below.
