"It is with profound sadness that I am confirming that the legendary, iconic performer, Prince Rogers Nelson, has died at his Paisley Park residence this morning at the age of 57," his publicist said in a statement to ET. "There are no further details as to the cause of death at this time."

Prince helped launch Carmen Electra's career, even gracing her with the moniker Carmen in place of her real name, Tara Leigh Patrick. She released a statement to ET about the difficult lost of her longtime friend.

"I was so shocked and heart broken to hear about the loss of my mentor, Prince," she said. "The world has lost a truly incredible spirit and musical genius. What a blessing it is to be one of the chosen ones who had the chance to work so closely with him. He gave me my name, he believed in me, and he has inspired an entire generation. I will always love him... 'Sometimes It Snows In April.'"

Singer Toni Braxton also looked back on the storied yet private life of her dear friend and confidant. "Throughout the years, and all of my crises, Prince was always there for me," she told ET in a statement. "During my bankruptcy, he asked me to go on the road with him. When I made the decision to retire, he called me and told me that I had a gift and that I could not stop now. He was like my big brother, always looking out for me. No other artist has meant as much to me as he did."

"He was always there for me giving me his support. I will miss him so much," she added. "He was as special of a friend as he was a brilliant talent. My condolences to his family. Good night, sweet Prince."
