Despite having reeled in nine Grammy Awards and multiple nominations over the past five years, Alicia Keys was surprised to hear of her five additional nods for this year's 48th annual honors, including best song ("Unbreakable”) and best album for her 2005 live set, "Unplugged” (J Records).

"I was very, very shocked actually,” Keys tells Billboard.com. "I know people look at me like, ‘What are you talking about? Why would you be shocked?' but I didn't quite think that ['Unplugged'] would make it with the timing and I wasn't even on that page. I wasn't thinking about the Grammys. I forgot they come up in February.”

The singer is also up for best female R&B vocal performance ("Unbreakable”), best traditional R&B vocal performance ("If I Was Your Woman”) and best R&B performance by a duo or group with vocals ("If This World Were Mine,” featuring Jermaine Paul) . The awards will be handed out Feb. 8 at the Staples Center in Los Angeles.

"Unplugged” has sold over 1 million copies in the United States, according to Nielsen SoundScan, while its predecessor, 2003's "Diary of Alicia Keys,” has sold 4.4 million. Both albums debuted at No. 1 on The Billboard 200.

Keys says she learned of her nominations one morning while preparing to go on the set of the film, "Smokin' Aces," due later this year in theaters.

"I turned on the radio just to try to get myself going and it was like, 'Alicia has five nominations' and I was like, ‘Word?'" she laughs. "I was kind of banking on being home in my bunny slippers and watching TV but it doesn't look like that's going to happen, which is a wonderful thing. I'm just going to go there and feel blessed to have my music appreciated and whatever happens, happens."
