Former CNBC anchor Nicole Lapin has landed billionaire Internet entrepreneur Michael Rubin. Lapin, 27, who launched her own financial news production company “Nothing but Gold” after leaving CNBC in September, started dating Rubin, 41, in July, a month after he separated from wife Meegan with whom he has a daughter, sources say. They’re living together in Union Square. Lapin’s rep denies chatter that Rubin, who appeared on CBS’ “Undercover Bosses,” bankrolled her venture, saying, “It is self-funded.”
