The remake of 1985's "We Are the World" made its world premiere Friday during the opening ceremony of the Winter Olympics.

Organizers Lionel Richie and Quincy Jones introduced the song via video and said the money raised by its sales will provide food, shelter and medicine for the Haitian people.

A three-minute version of the video aired Friday and the full seven-minute video (below) will debut on Saturday.

The video, directed by Paul Haggis, shows the devastation in Haiti. It also shows some of the 85 artists who gathered to record the track earlier this month in L.A.

Teen heartthrob Justin Bieber opens the song. Also featured are Wyclef Jean, Will.i.am, Jennifer Hudson, Nicole Scherzinger, Sugarland's Jennifer Nettles, Barbra Streisand, Celine Dion, Fergie, Josh Groban, LL Cool J, Nick Jonas, Lil Wayne, Jeff Bridges, Kanye West and Miley Cyrus.

Janet Jackson also sings a duet with Michael Jackson's original vocals. Michael co-wrote the original song with Richie.

"We Are the World" is available now on iTunes.

"American Idol" judge Simon Cowell confirmed to reporters Wednesday night at the National Television Awards in London that he's in the process of securing acts for a charity single, the proceeds of which will aid the victims of last Tuesday's earthquake in Haiti.

Cowell has not yet confirmed who will participate on the track, but The Sun speculated that he would likely secure "X Factor" sensations Leona Lewis and Susan Boyle, with Beyoncé and Lady Gaga also mentioned as possibilities.

Nicole Richie is pregnant with her second child by beau Joel Madden, but confesses that the lovebirds aren't in any rush to get married.

The socialite dished about her relationship with the Good Charlotte rocker on "Larry King Live," saying that while she and Joel want to tie the knot, they don't feel the need to do so just because they're having a second child. "I think for both of us, we are going to do it because we want to, not because that's what you do," Nicole said.

Richie was joined by her father Lionel Richie on the program, where the singer gushed about Nicole's transformation from party girl to Hollywood mama. "I'm so proud of her right now -- there is such a pride that she has turned this corner. She is an amazing mother. I want the world to know where she is."

Nicole gave birth to daughter Harlow in January 2008.
