Meredith Vieira accidentally curses on "Today" show

Meredith Viera, who was filling in for Kathie Lee Gifford on the fourth hour of "Today," accidentally uttered the phrase, "Oh s--t," on air Friday morning.

Vieira, who was holding a fruit drink sitting next to co-host Hoda Kotb and Al Roker, accidentally dropped her cue cards when she dropped the expression.

She immediately apologized saying, "Oh, my gosh, I'm so sorry, I'm so sorry."

A couple seconds later a bleep came on and Kotb joked, "A little late for the bleep."
