Adele may be rolling deep with Grammy nominations

She likely won't get "21," but Adele is poised to take the biggest bulk of nods when the Grammy nominations are announced Wednesday night.

The British singer-songwriter has had a great year, thanks to her sophomore album, "21." The mournful album about a failed relationship is the year's best-selling disc with over 4.5 million copies sold. It has resulted in two smash singles, "Rolling in the Deep" and "Someone Like You."

The Recording Academy will likely add to Adele's achievements. She is a strong contender to get bids for album of the year and for song and/or record of the year.

But she's not the only favorite for top nominations. Taylor Swift's "Speak Now" is a possible contender for album of the year, as is Tony Bennett's "Duets II."
