Miss Universe and former Boston University student Olivia Culpo has been making rounds since winning her crown. She was on “The Covino & Rich Show’’ late last week (pictured at right) and told Medford’s Maria Menounos on TV’s “Extra’’ that she is not dating Olympic swimmer Ryan Lochte, despite rumors implying otherwise. “Rumors are rumors,’’ she said. “At the end of the day, we’re just friends and I’m happy with that.’’ Culpo also shared a beauty tip on “Extra.’’ She said that we should all drink a lot of water, especially during the winter. Sounds easy enough.
