Jennifer Hudson hit plenty of emotional notes during the 51st annual Grammy Awards.

The singer collected the Sunday's first major award, best R&B album for her self-titled debut, making reference to her slain family in a tearful acceptance speech.

"Thank God, who brought me through," Hudson, 27, said on the stage of Los Angeles's Staples Center. "I'd like to thank my family in heaven – and those who are here today."

Hudson also thanked fiancé David Otunga, who told E! before the show, "the last few months have been an ordeal and it just brought us closer," for his support.

Later, the Grammy winner fought back more tears after earning a standing ovation for her power ballad "You Pulled Me Through." Hudson belted out the song in a black, sequined sheath with the backing of a choir. "I was in the darkness. I was out in the cold," she sang. "You reached out your arms to me ... pulled me back from the edge."

Major Winners

The night's biggest honor went to Robert Plant and Alison Krauss, whose Raising Sand was named album of the year. "I'm bewildered. In the old days we'd call this selling out," Plant said while accepting the award. "But I think it's a good way to spend a Sunday." The duo also won record of the year for their song "Please Read the Letter."

Eight-time nominee Lil Wayne picked up some high-profile trophies, including best rap album for Tha Carter III. In a pre-telecast ceremony, the rapper also nabbed awards for best rap solo performance for "A Milli" and best rap song for "Lollipop." Meanwhile, seven-time nominees Coldplay won song of the year for "Viva la Vida," as well as best rock album and best pop duo/vocal group.

British soul singer Adele Adkins bested the Jonas Brothers in the best new artist category.
