I Gotta Feeling Black Eyed Peas
See the 10 best dresses at this year's Grammy Awards.
The singer later wore a bodice and tights for her performance of 'Drunk In Love' with husband Jay Z.
Her son David Banda wore a matching suit.
For her acrobatic live performance Pink wore a lace bodice and fishnet tights.
Kelly kept her gown simple but accessorized her look with rings, black nails and a back crucifix she borrowed from her father Ozzy. The outfit worked well for her. The 'Fashion Police' presenter has clearly picked up lots of tips working on her TV show.
Perry changed dresses four times. She wore a witch-like outfit for her performance, a maroon short dress with a snake design and at the after party she went for a light blue Disney princess type of gown.
Ciara admitted having a club sandwich and fries before arriving at the awards and said she's experiencing food cravings and going along with them!
Alicia Keys not only looked beautiful but she was clearly beaming at the awards, probably something to do with winning Best R&B Album for 'Girl On Fire'.
The 'Pitch Perfect' actress was one of the classiest on the red carpet.
Ora matched her dress with strappy sandals. The singer posed on the red carpet with Calvin Harris. Does that mean their relationship was back on?
For her 'All Too Well' performance Swift changed and wore a draped Grecian gown.
