Alicia Keys 'amazes' at album launch party

Alicia Keys danced the night away to "old-school hits" at her album launch party on Tuesday night.
The singer and her guests celebrated the release of Girl on Fire in style at The Box venue in New York City.
Clad in a leather dress with her hair in a funky quiff, the 31-year-old seemed to make an impression on attendees.
"[Alicia] looked amazing," a guest gushed to Us Weekly. "She was talking about how happy she was that the album got such good reviews and saying how she really wanted to 'tap into her heart' for this one. They played a lot of old-school hits and songs from the album. Everyone danced and celebrated."
Famous pals joined the mother-of-one for the festivities, including A-list couple Beyoncé and Jay-Z.
Entertainment by DJ Cassidy and DJ Runna got everyone up on their feet, and apparently the superstar couple left the booth where they were sitting to join Alicia on the dancefloor.
The Brand New Me singer was also accompanied by husband Swizz Beatz, who took to the mic with DJ Cassidy to provide his own musical entertainment.
Other guests at the bash included Jason Derülo and girlfriend Jordin Sparks and Justin Timberlake minus new wife Jessica Biel.
Earlier in the day Alicia had been busy with an intimate performance for iHeartRadio in aid of Hurricane Sandy victims.
The star took her son Egypt up on stage at the charity concert and sang smash-hit No One for her audience.
Superstorm Sandy hit the east coast of America last month, leaving devastation in its wake.
