Bonnie McKee at The 57th Annual GRAMMY Awards

American music artist and songwriter Bonnie McKee attended the 57th Annual Grammy Awards in LA, California and dazzled in her sexy attire.

The singer wore a purple slinky gown that had a clinging bodice with a draped skirt featuring a small train.

Bonnie styled her backless look with many long gold necklaces and kept her ash blonde hair side-parted and loose. A matching purple lip topped off her sultry attire for the night.
