OHIO: Katie Holmes and Jamie Foxx are still dating despite denying they’re an item, claim sources. The two stars were first linked last summer when they were spotted dancing together at a Hamptons gala. Friends say they haven’t gone public with their relationship because they still don’t feel ready. “It’s the worst kept secret in Hollywood. When they were first linked last August they weren’t ready to make their relationship public. They were both worried about Tom’s Cruise reaction - after all, he introduced them when he was still married to Katie,” a source divulged to British magazine Grazia.–BTG
