Pedro says his world’s a bit darker now that O’Hara is gone … before calling her the “one and ONLY” Catherine O’Hara.

Andy Cohen shared a picture of O’Hara from the Canadian sketch show, Second City Television, on which many other big names — like Martin Short and John Candy — got their big break. Cohen says he “fell in love” with O’Hara after first seeing her on the show.

“It’s Always Sunny in Philadelphia” star Kaitlin Olsen shared her grief, as did Lea Thompson, Katie Maloney, Lisa Ann Walter, and many more, who also paid tribute to her — so did her “Home Alone” son, Macaulay Culkin.
