They have performed together on the Grammys. Now Lady Gaga and Sir Elton John are taking the Macy's stage.

The pop icons are teaming on a limited-edition line of clothing and accessories called Love Bravery which will be sold exclusively beginning April 30 on macys.com and in about 150 Macy stores beginning May 9.

Twenty-five percent of each purchase will support the charities championed by the celebrities, the Born This Way Foundation and the Elton John AIDS Foundation. The message behind the Love Bravery collection is to "inspire compassion and combat prejudice," according to the performers.
