Pop singer Simone Battle of the girl group G.R.L. has died, the victim of an apparent suicide.

According to the Los Angeles coroners office, the 25-year-old The X-Factor finalist was found dead at her West Hollywood home by her boyfriend Friday morning.

The singer’s father, Anthony Battle, reportedly told TMZ that he was unaware his daughter was battling depression, but said it was “possible she may have had an invisible disability”.

Battle’s record company and management team confirmed the singer’s death in a joint statement released on Saturday.

“We are deeply saddened by the tragic news of the loss of Simone Battle of G.R.L.,” said the statement from Reign Deer Entertainment, Kemosabe Records, RCA Records and Pussycat Dolls founder Robin Antin.

“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.”
