Jenna and Barbara are being tossed out of Argentina -- not by the actual country, but by the pissed-off U.S. diplomats in Buenos Aires.

Why? Because their drunken antics and usual Bush-inspired chaos have ruined the buzz for new American Ambassador Anthony Wayne, who expected the whole country to applaud his pointless appointment. Instead, the Argentine press has gone Bush Twin Crazy.

The local tabloids say Barb and Jenna are literally running naked through the halls of their exclusive hotel, while the twins' Secret Service team has apparently completely abandoned the gals. Many more tawdry details -- including a double assassination attempt -- are now in this brand new breaking update.
