Ellen DeGeneres is mourning the tragic loss of one of her favorite guests. You may recall that Tayt Andersen made several appearances on The Ellen DeGeneres Show over the years, starting in 2013. While on the daytime talk show, his mom, Chrissy Andersen, explained that he was born without the left side of his heart and has been in and out hospitals most of his life. He even had 12 surgeries before the age of 9. Jeez.
