Before Sunday night's Grammy Awards, five of this generation's most revered singers gathered at Los Angeles' Staples Center to fine-tune their highly anticipated salute to the Queen of Soul, Aretha Franklin.

Of course, after the Super Bowl national anthem debacle, all eyes and ears will be on Christina Aguilera at the Grammys, where she'll reportedly sing Franklin's "Ain't No Way." Aguilera, pictured at the center mic, will share the stage with four other vocal divas (from left): Grammy winners Yolanda Adams, Martina McBride and Jennifer Hudson, plus newly-Grammy-nominated frontwoman for Florence and the Machine, Florence Welch.

Hudson couldn't hold back her excitement about the performance.
