There was some drama behind the scenes of Bravo’s premiere of “The Real Housewives of New York City” before the show even hit the air, as the reality stars jockeyed to get closest to Bravo host Andy Cohen.

Said a spy at NoMad hot spot the Seville, which held a party to celebrate the series, “Ramona Singer arrived late and ran onto the carpet, pushing Luann de Lesseps out of the way to get a spot next to Andy. Luann retreated away but was persuaded to join the group again and took her original place next to Andy.”

Another source observed, “Andy only came to walk the red carpet because he had to head to the studio for his late-night show, ‘Watch What Happens Live’…But within minutes of his arrival, Ramona started to push the other ladies — specifically Luann — out of the way so that she could stand next to him in cast pictures.”

Singer and Bravo did not get back to us.

Also in attendance were Tinsley Mortimer, Carole Radziwill, Dorinda Medley and Sonja Morgan. Bethenny Frankel was instead headed to Australia.
