Where did you find this?

I can´t find it anywhere, and they have got loads of people presenting it seems..

Nino it was reported on MTV’s official site:

The list of presenters has also gotten longer, adding Katy Perry, Justin Timberlake, Jesse Eisenberg and Andrew Garfield, who join already onboard presenters Ke$ha, Nicki Minaj, Emma Stone, Penn Badgley, Trey Songz, Ashley Greene, Selena Gomez and Ne-Yo. More performers and presenters will be announced later.

Its nice to see him back on a musicrelated event even if its for a movie promotion.

uh i cant find his name either on the mtv link

I don´t see the name of Justin Timberlake on MTV’s official site. I click the link but isn´t Justin like presenter

Its weird…his name did appear on the article before.
Here is the original article: http://www.rockol.it/news-152199/Eminem-To-Perform-at-2010-MTV-VMAs

I’m asking MTV on twitter whether or not he is appearing. Doubt they’ll reply but I tried anyway.

That is weird. Maybe they were going to be surprise presenters and someone jumped the gun. I see them being there since it will be getting close to the release date of the SN.
