Battle's music career started to take off after her run on "The X Factor" in 2011.

She signed on as one-fifth of the pop group G.R.L., which is best known for its collaboration with Pitbull on "Wild Wild Love."

G.R.L. was started by Pussycat Dolls founder Robin Antin as the next generation of her original group.

The group commemorated Battle on its Twitter account, writing: "Words cannot express the depth of our loss. Simone's incredible talent was only surpassed by the size of her heart."

Former Pussycat Doll Nicole Scherzinger, who knew Battle from their time on "The X Factor," dedicated her performance to the late singer in South Africa on Saturday night.
