British heartthrob, Robert Pattinson, is one among several famous Hollywood celebrities such as Julia Roberts, Tom Hanks, Michael Douglas, Gwyneth Paltrow and Samuel L. Jackson who joined forces at the star-studded "Stand Up 2 Cancer" telethon in Los Angeles.

According to reports, the 26-year old "Twilight" actor appeared at the somber televised event together with Justin Timberlake, Matt Damon, Halle Berry and thyroid cancer survivor Sofia Vergara and all of these famous stars lend their support to the campaign which was launched by the late "Spiderman" franchise producer, Laura Ziskin.

In 2011, Ziskin lost her battle against breast cancer and she was remembered by with a special video tribute that featured the stars from the film franchise like Tobey Maguire and Emma Stone.

"Like every great hero, she had a vision and she set us into motion. And now it's up to us to continue moving forward to achieve her dream," Emma Stone said in the video clip.

Meanwhile, Hollywood icon, Michael Douglas, has urged the viewers to give donations in order to help finding a cure for the killer illness and save the other victims from the disease. The 67-year old "Fatal Attraction" actor also happens to be a throat cancer survivor.

"I picked a fight with the wrong guy! Cancer didn't bring me to my knees, it brought me to my feet. I stand tonight because I want to be part of this effort to find an end to cancer. This is possible. Cancer's in for one hell of a fight," Douglas told the audience.

Country singer Taylor Swift fought back her tears as she made a debut of a new song called "Ronan" and it was inspired by a three-year-old boy named Ronan Thompson, who died of the illness last year. The song was made available for download after the show and all of the proceeds will be donated to the cancer charity.

Other music artists like Alicia Keys and Tim McGraw also took the stage during the telethon. The British rock band Coldplay dedicated their performance of "Paradise" from their concert in France earlier that night to the cancer cause.

Felicity Huffman, Joe Manganiello, Ray Romano, Kobe Bryant and gold medal-winning Olympic gymnast Gabby Douglas manned the phones and talked to those who were calling in to pledge their donations throughout the night.

The Friday telethon event was produced by Gwyneth Paltrow and she took over the telethon for her good friend Laura Ziskin. Before the show, the actress also opened up about losing her father Bruce Paltrow in a battle with cancer back in 2002.

"It's been almost a decade now and I'm sort of more used to the fact that he's not here in physical body. But I definitely feel his presence, and I think he would be really happy that I'm here tonight doing this and trying to spare other people from what he went through," Paltrow said.

Gwyneth Paltrow has also announced her plans to take the cancer crusade to London and carry out a similar event on October 12.
