Have girl group G.R.L. split up for good?

That's what fans are wondering after two members -- Emmalyn Estrada and Paula van Oppen -- removed "GRL" from their Twitter handles, according to Idolator. Emmalyn changed her Twitter handle from '@GRLEmmaLyn' to '@EmmalynEstrada,' while Paula switched her alias from '@GRLPaula' to '@EyesThatLightUp.'

Adding fuel to the fire that G.R.L. no longer exists was a cryptic tweet by band member Lauren Bennett. While Lauren still goes by the Twitter handle '@GRLLauren', the singer wrote the following:

Indeed, the future of the girl group has been in question ever since the fifth member  of the group, Simone Battle, committed suicide at the age of 25 last September. In the aftermath of Battle's death, the band released a statement, saying, "Words cannot express the depth of our loss. Simone’s incredible talent was only surpassed by the size of her heart. We will carry her memory with us in everything we do.”

In January, the four remaining band members released a video and song titled "Lighthouse" as a tribute to Simone.

G.R.L. was originally formed in 2011 by Pussycat Dolls founder Robin Antin before going through several lineup changes. In 2014, the group released their first and ultimately only EP, which featured the hit single "Ugly Heart."

We wish the girls of G.R.L. the very best in their future endeavors.
