SOMEONE should tell Cassie that she could do better than Sean "Diddy" Combs. He's publicly announced that his on-and-off flame is not the only woman in his life, but she's not moving on. Our spies saw a sullen Cassie "looking smokin' hot," at the Empire Hotel the other night. But it wasn't enough to catch the eye of Diddy, who has emphatically shot down rumors that they're exclusively dating. "Diddy spent the entire time with his entourage while she was being walked around by one of his assistants," said our source. "She never smiled, and she kept looking over at him."
