Stars Unite to Fight Against Cancer

A slew of stars showed off their philanthropic sides when they attended the Stand Up to Cancer event in LA on Friday night. The annual telethon brought out Shannen Doherty and her husband, film producer Kurt Iswarienko and longtime couple Tom Hanks and Rita Wilson, who recently returned from NYFW. Bradley Cooper, Emma Stone, and Kristen Wiig were all in attendance as well, and Celine Dion paid tribute to her late husband, René Angélil, who passed away from throat cancer in January, by wearing a t-shirt with the words "MY LOVED ONES #Reasons2StandUp" written across it and giving a beautiful performance of her new song "Recovering."
