Hugh Jackman and Lady Gaga have paid tribute to their acting coach Elizabeth Kemp, following her death from cancer.
Kemp, who worked with Bradley Cooper and Jackman and recently taught Gaga for Cooper's remake of "A Star is Born" died over the weekend at age 65, reported Entertainment Weekly.
Gaga dedicated a song to her tutor at a concert in Boston. The singer called Kemp "strong, wise and cool".
"What was incredible was that Bradley told me Elizabeth died with such dignity. She knew she was going to go but he told me it was very graceful," Gaga said to the crowd.
"She would have wanted each and every one of you to feel so grateful... She was such a strong woman. She used to ask me all the time to go back to the hardest thing in my heart for the stage."
Jackman tweeted, "Elizabeth Kemp I celebrate your life and am profoundly grateful to have spent precious time with you."
He also shared the video Gaga paying tribute to Kemp on stage at Boston's Fenway Park.
Kemp based her classes on the acting method created by Konstantin Stanislavsky and was also inspired by famed coach Lee Strasberg.
Her death was announced via official Facebook page by Rosa Asor Morelli, a co-administrator 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.
