Rob on board for Haiti Telethon

Robert Pattinson is on board.

I just got word that the Twilight star has signed on for Friday's Hope for Haiti telethon. As of right now, it looks like Rob will be the sole presenter in London with performances by Jay-Z and Bono.

Stateside performers—some announced and others not—will include:

Taylor Swift, Alicia Keys, Christina Aguilera, Shakira and Bruce Springsteen are among those who will perform live during the two-hour benefit, which will air on all the major television networks (including our very own E!).

 Other mega-celebs who will present and/or help in the phone banks are Jennifer Aniston, Jake Gyllenhaal, Brad Pitt, Anna Kendrick, Sandra Bullock, Zac Efron, Bradley Cooper, Renee Zellweger, Chris Pine, Courteney Cox, David Arquette, Colin Farrell, Jon Hamm, Gabby Sidibe and Emily Blunt, among many others.

No word yet on Kristen Stewart and Taylor Lautner, but as I was the first to tell you Hollywood's hottest vampire movie trio is a very wanted group for the telethon because of the impact they would have with young people.

Also on organizers' wish list are—no surprise—Oprah Winfrey and Angelina Jolie.

Clooney is set to host from Los Angeles with Wyclef John in New York City and CNN newsman.source
