LaBelle, who started her career as a member of The Blue Belles has been in the limelight since the 1960s as a singer. From her ’70s rock-influenced female vocal group Labelle, to her solo ‘New Attitude’ in the ’80s and a recent run on Broadway in the musical ‘Fela!’ she is considered as one of the great pop sensations of the last 50 years.

With a string of hits including ‘Lady Marmalade’ and the No. 1 hit ‘On My Own,’ a duet with Michael McDonald, the legendary songstress, humanitarian and entrepreneur will receive BET Award’s highest honor – the Lifetime Achievement Award.

The BET Awards will also honor comedian Steve Harvey for his various philanthropic efforts with the Humanitarian Award.

Hosted by comedian Kevin Hart, the BET Awards will feature performances by Jill Scott, Alicia Keys, Lil Wayne, Drake and Chris Brown and air live on June 26, from the Shrine Auditorium in Los Angeles.

Pink, Celine Dion, Natalie Cole, the Jonas Brothers, Kanye West, Tony Bennett, Jennifer Hudson, Akon and other musical luminaries stood shoulder to shoulder on risers at Henson Recording studios, singing their hearts out and hoping to help Haiti.

At one point during the session, the musicians broke out into an acappella version of the pop classic “Lean on Me.”

True to her diva reputation, Barbara Streisand recorded her solo over and over, completely absorbed in the recording process and stopping only to correct her pitch.

Rapper Lil’ Wayne was told he would do Bob Dylan’s part in the original song.

“I said, ‘Are you kidding?”’ he said. He felt blessed to record the song but admitted, “I don’t know how to sing.”

Asked how the earthquake had affected him, he said he had Haitian friends in Miami who lost relatives in the disaster.

“I think it’s amazing what’s been done for Haiti, but I think it’s amazing what hasn’t been done for New Orleans,” said the Crescent City native.

Quincy Jones, who produced the 1985 anthem, announced last week that he planned to redo the song to benefit recovery from the deadly Jan. 12 earthquake in Port-au-Prince.

Written by Michael Jackson and Lionel Richie, the original “We Are the World” thundered up the charts when it was released on the radio and in record stores in March 1985.

An unprecedented number of top pop musicians gathered at A&M the night of Jan. 28, 1985, following the American Music Awards, to record the tune. The song featured 45 American superstars, including Jackson, Richie, Stevie Wonder, Tina Turner, Ray Charles, Bruce Springsteen, Diana Ross, Bob Dylan and Cyndi Lauper.

None of the original performers returned for the re-record.

The 1985 record raised more than $30 million for USA for Africa, a nonprofit organization founded by the singers to fund hunger relief in African nations.

While reporters watched a video feed of the session in a nearby room, stars like West mingled outside with friends and greeted his buddy, Snoop Dogg, with a hug.

Nicole Richie and “Good Charlotte” singer Joel Madden showed up with their 2-year-old daughter Harlow, whom Madden bounced in his arms to the beat of the music.

Julianne Hough from “Dancing with the Stars,” who is also a country singer, said she felt honored to lend her voice to the effort and sing next to so many talented musicians.

“It’s just iconic. Celine (Dion) is just so gracious and amazing and such a pro,” she said.
