Miss Universe Olivia Culpo denies she’s dating Mr. Personality, Olympic swimmer Ryan Lochte. Culpo, who took the Universe crown last month, told “Extra” host Maria Menounos of talk she was seeing Lochte, “Rumors are rumors. At the end of the day we’re just friends, and I’m happy with that.” Culpo, who insists she is single, was more enthusiastic when it came to pageant king Donald Trump: “Mr. Trump is an amazing person . . . I think I have the best boss.”
