The 18-year-old actress/singer, Selena Gomez stopped into Z100 and talked about Katie and her
Ex Jesse McCartney and how she used to hate her for going out with him.
“But I have to agree with them sometimes. I loved Jesse McCartney. I was obsessed with him. He dated Katie Cassidy when he was 16 or 17. I hated her, absolutely hated her. I was mortified that he was with Katie and I wanted to be with him. He was my screen-saver! I just did a movie (Monte Carlo) with Katie Cassidy and she was the nicest person ever.”
