Neil Patrick HarrisNeil Patrick Harris insists that, no matter what you've heard, he will not -- wait for it -- open this Sunday's Oscar ceremony.

Yesterday, Deadline Hollywood dropped an "Oscar Spoiler" (so we're spoiling that now, too?) that the former Emmy host and 'How I Met Your Mother' star would join Martin Short onstage for a musical number to kick off the show on March 7th.

"Anything can change, but that unlikely duo has been rehearsing an original opening song and dance routine that is one of two big production numbers choreographed by executive producer Adam Shankman," it reported.

But within hours, NPH went on a Twitter counteroffensive, denying the report with a little added jab at our favorite award show saboteur. Neil Patrick HarrisNeil Patrick Harris insists that, no matter what you've heard, he will not -- wait for it -- open this Sunday's Oscar ceremony.

"I will not be performing a duet with Martin Short to open the Oscars," Harris tweeted. "Misinformation, I'm afraid. Should I maybe pull a Kanye, mid-show?"

So who's telling the truth?

As Fleming reports, Short
has a long relationship with the broadcast's musical director Marc Shaiman, who is arranging the opener, so there may be a little Hollywood smoke-screening going on here. But then again, part of Harris' charm is his transparency. From his personal life to his recent appearances on 'American Idol' and Twitter spat with Kevin Smith, Harris has earned his stripes with fans by being up-front, accountable and usually hilarious.

So if he says the opening musical number is a no-go, we'll go ahead and believe him.
