Celebrities paid tribute to Elizabeth Kemp on social media.

On Saturday, Kemp passed away at 65. Her death was announced on Facebook by Rosa Asor Morelli, admin of the page. "With a heavy heart, I have to share the news of the sudden loss of our beloved Elizabeth Kemp It is a shock, no doubt, for all of us that have had the privilege to have her as Mentor, Teacher, Friend," she wrote.

Kemp was a popular celebrity mentor and coach. Thus, Lady Gaga and Hugh Jackman took some time to pay tribute to the late "He Knows You're Alone" star. "Elizabeth Kemp I celebrate your life and am profoundly grateful to have spent precious time with you," the "Wolverine" actor wrote.

The "Million Reasons" singer remembered how Kemp inspired her to dream again. "She loved you so much and talked about you and lit up when we worked. She helped me want to dream again and know it's power. #ElizabethKemp," Gaga wrote.

According to Deadline, Kemp was mentored by Elia Kazan and was a member of the Actors Studio for three decades. Kemp was also a member of the acting faculty at the Actors Studio Drama School at Pace University and taught at the Lee Strasberg Institute and Susan Batson's Black Nexxus.

Kemp used the "dreamwork" technique in coaching her students. This is a Jungian approach that utilizes the student's dream. "In the Method, we revisit something we lived through," she told The New York Times in 2009. "But there are still pockets in the unconscious or the psyche that have a residue of feelings — feelings that have not at all been expressed in life."

Kemp also made a number of appearances on TV. In the 1970s she debuted in "Love of Life" and appeared in 1980 horror flick "He Knows You're Alone" featuring young Tom Hanks. She also appeared on TV series "L.A. Law," "Law & Order" and "Thirtysomething."
