Sofia Vergara’s on-again boyfriend Nick Loeb is firing back at a wild report which claims he engaged in cocaine-fueled orgies with prostitutes while dating the Colombian stunner. Two prostitutes told the National Enquirer they had slept with Loeb, with one — named “Bianca” — saying: “He’ll party with anywhere from two to five girls, usually in luxury hotel penthouses, with porn playing on all the TVs, lines of cocaine laid out and liquor flowing like water.” But furious Loeb — who still harbors political aspirations after flirting with a US Senate run last year — told us in a statement: “I am mortified that false illicit behavior has been attributed to me. It’s hurtful and unfair. My first priority is to protect the people I love, and I hope they are not impacted by these lies and irresponsible reports.” Sources tell us Onion Crunch baron Loeb is now considering legal recourse. We revealed that he and Vergara briefly split in early May after more than two years together, following a series of fiery arguments. But they reconciled in recent weeks and have since been seen out in New York looking happy together.
