Jennifer Aniston has faced criticism and hate from celebrities like Kristen Stewart, Bill O'Reilly, Piers Morgan, and John Mayer. Stewart claimed that Jen's popularity was due to her feud with Angelina Jolie and questioned why she always made headlines despite being less talented and beautiful than other actresses. While Aniston rarely responds to such comments, she did clap back at O'Reilly for insulting single mothers in the film 'The Switch'. Despite facing hate from peers, Aniston remains a beloved Hollywood star who receives immense support from her fans.
