LOS ANGELES: KALEY Cuoco dumped Henry Cavill because she was overwhelmed by the relationship. The pair split up last month following a brief romance and friends of the 27-year-old actress said the relationship was difficult for her as she found it difficult to deal with the constant attention. “She just got overwhelmed with the very public Superman relationship. She’s not used to that much attention and chaos in her life,” a source said. Kaley is now dating tennis player Ryan Sweeting and is much happier with this low-key romance. “She thinks Ryan’s really hot and a nice guy,” added the source. –SP
