Cougar alert! “Real Housewives of Beverly Hills” star Taylor Armstrong had a fun night in the Hamptons recently with “Hell’s Kitchen” chef Seth Levine. The two met at Levine’s East Hampton hotspot Georgica, where Armstrong shared dinner with magazine editors and Levine provided the delectable tasting menu. But as the vino flowed, things got more friendly, spies said. Patron Dina Lohan told Armstrong, “You better take care of him,” as she left the lounge, and Armstrong obliged. The married reality show star accompanied Levine onto the jam-packed dance floor for some close-contact grooving, eyewitnesses said. A rep for Armstrong said, “This is absolutely not true.” We can expect more Georgica revelry when Samantha Ronson spins at the annual Blue & Cream party tonight; Stephanie Pratt and Kelly Bensimon are among those expected this weekend.
