NEW YORK - It looks as though Rosie O'Donnell won't be facing off with Larry King after all.

The acid-tongued talk-show host, who famously clashed with Elisabeth Hasselbeck on "The View," announced on her blog Wednesday that talks to give her a prime-time show on MSNBC had fallen apart.

Saying the development was "just as well," O'Donnell wrote in her usual shorthand style: "poof/my career as a pundit is over/b4 it began."

The deal would have placed O'Donnell in the 9 p.m. slot, she said, opposite CNN's "Larry King Live" and Fox News Channel's "Hannity & Colmes." Fox News dominates prime-time ratings for cable news channels, according to Nielsen data; CNN is second, and MSNBC is a distant third.

A day earlier, an NBC executive had cautioned the sides were far from a done deal.

An MSNBC spokesman had no comment Wednesday night, and a call to O'Donnell's spokeswoman went unanswered.

O'Donnell hosted her own daytime talk show from 1996 to 2002. She also produced a Broadway musical and founded a short-lived namesake magazine before her tempestuous run on ABC's "The View."

Although she was at "The View" for less than a year before leaving in May, her boisterous, opinionated style and tangles with Hasselbeck, a former "Survivor" contestant, were credited with boosting the talk show's ratings.
