"Words cannot express the depth of our loss. Simone's incredible talent was only surpassed by the size of her heart," G.R.L. tweeted on Sept. 6. "We will carry her memory with us in everything we do."
Battle, an X Factor alum, was one of five members of girl group G.R.L., whose debut self-titled EP was released on July 29 through Kemosabe Records/RCA Records. After getting some shine by collaborating with Pitbull on the Top 40 hit "Wild Wild Love," the act released the single "Ugly Heart," produced by Dr. Luke and Cirkut.
G.R.L. was created by choreographer/director Robin Antin as a reboot of sorts of the Pussycat Dolls, which disbanded in 2010. The group also includes members Lauren Bennett, Emmalyn Estrada, Natasha Slayton and Paula Van Oppen.

G.R.L.’s management company Reign Deer Entertainment, Antin, Kemosabe Records and RCA released the following statement following Battle’s death.
“We are deeply saddened by the tragic news of the loss of Simone Battle of G.R.L. Simone was an exceptional young talent and human being, and we are all devastated to learn of her passing. Our thoughts and prayers are with her family and loved ones at this time.”
Battle’s last tweeted was on Sept. 2 that she was heading out to see artist Evan Mellows perform at the Bootleg in Los Angeles.
Battle competed on The X Factor in 2011, auditioning for the judges with the Pussycat Dolls song "When I Grow Up." She was mentored by Simon Cowell and was eliminated from the show in the first week.
Battle was also an actress, having appeared in episodes of Everybody Hates Chris and Zoey 101. She joined G.R.L. in 2013 and had released several singles of her own.
