Headed out to celebrate one of the great talents in music, stars of all sorts came out to attend the “You’ve Got a Friend… A Celebration of Carole King and Her Music” concert special in Los Angeles, CA on Tuesday (December 4).

Glamming up the Dolby Theatre red carpet was fellow songstress Katy Perry, who looked striking in a leg baring emerald green gown with black embellishments.

Also on hand to join in on the collaborative music festivities were country star Vince Gill, “Breath of Heaven” singer Amy Grant and John Legend.

Quincy Jones and Jack Nicholson co-hosted the one night only concert benefiting Paul Newman’s The Painted Turtle Camp.
