He was a little early for breakfast.

An off-duty cop was arrested for drunken driving after he slammed his car into the front of Tiffany’s flagship Fifth Avenue store at 3 a.m. today, police said.

The wreck happened as NYPD officer Raphael Ospina, 27, a cop since 2004, was heading east on 57th Street. He collided with a private garbage truck that was heading in the opposite direction and making a left turn onto Fifth Avenue south.

Ospina's Chrysler 300 sedan, with two passengers inside, jumped a curb and hit the famous façade of the legendary jewelry store.
