Sly and Arnold — enemies turned best pals

Former “enemies” Arnold Schwarzenegger and Sylvester Stallone continued to hang tough together in New York after the premiere of their movie “Escape Plan.”

The muscled pair was spotted at Strip House downtown, dining with Planet Hollywood founder Robert Earl and a table of execs from Lionsgate.

The group plowed through a magnum of cabernet plus steaks, sea bass and crab cakes. Spies saw Sly and Ahnold then emerge from the restaurant with unlit stogies in their mouths.
