Alleged actor Josh Duhamel was escorted off of a plane after refusing to turn off his BlackBerry yesterday. Hey ... there are crucial NBA scores to check, alright?

Duhamel was on a flight from New York to Kentucky when a flight attendant asked him to turn off his phone before takeoff. Indignant, he would not do so.

A passenger says he was "very rude," even "taunting the attendant." And you wonder why Steven Slater peaced out in hilarious, illegal fashion this summer.

DUHAMEL-NO, he won't go! Wait, actually he will ...

According to TMZ, the flight attendant asked Fergie's husband to turn off the device three separate times, and the third time, Josh laughed at his request.

Duhamel's reaction infuriated the attendant, who then called for backup. The plane, which was already on the runway, was turned back to the gate.

Officers boarded and escorted Duhamel off. Passengers were pissed, and rightfully so ... this was a bigger waste of time than any episode of Las Vegas.

Duhamel's rep told TMZ, "He's sorry." How moving.
