Singer Elton John has called Elizabeth Taylor a hero for her AIDS advocacy, the AP reported.

The legendary actress died Wednesday at the age of 79 in Los Angeles. She was laid to rest at a private service on Thursday.

Taylor became a leading advocate for AIDS research after the 1985 death of actor Rock Hudson from AIDS complications. She helped create amfAR, one of the world's leading non-profits dedicated to raising awareness and funds to end the disease.

The 64-year-old Sir Elton dedicated Don't Let The Sun Go Down On Me at a Wednesday concert.

“Today I lost a friend and you lost a hero named Elizabeth Taylor,” he told the audience.

“She stood up when no one was prepared to stand up and be counted against AIDS. She supported everybody in that with 1,000 percent of her body and her fiber. But most of all she loved people. She fought for the underdog. She was an incredible woman and I was privileged to have known her.”

“God bless you, Elizabeth. God knows how we're going to replace you.”

Singer Barry Manilow and fashion designer Kenneth Cole, amfAR's current board chair, have also praised the Oscar-winning actress for her contributions to the cause.
