The original line-up consisted of Bennett, Slayton, Estrada, Paula van Oppen and Simone Battle.

Their second single "Ugly Heart" gained international success shortly after the suicide of member Simone Battle.

In March 2011, Antin began holding auditions to find new girls to replace the departed members of The Pussycat Dolls.

"[3] An official picture taken from the ad showed five members: Lauren Bennett, Paula van Oppen, Vanessa Curry, Chrystina Sayers, and Erica Kiehl Jenkins.

[6] In July 2012, the line-up was announced consisting of Bennett and Van Oppen, with new members Natalie Mejia, Amanda Branche, and Natasha Slayton, thus confirming Jenkins and Curry's withdrawal from the group.

[7] In August 2012, publicity photos showed the "new" line-up including Simone Battle (from Season one of The X Factor USA) replacing Branche.

[8] In November 2012, it was revealed, through the hiring of Emmalyn Estrada, that Mejia was no longer part of the group, thus creating the official lineup of G.R.L.

[9] Mejia announced that she was expecting her first child with her husband, and due to her situation she made a choice to not continue with the group.

In February 2013, Antin officially announced that the girls will be making their debut as a brand-new group with a different name instead of replacing the departed members of the Pussycat Dolls.

[14] On September 10, 2013, in Brooklyn, New York, the group began a monthlong promotional tour partnered with Claire's and Westfield Malls meeting fans, visiting radio stations, and performing at select locations.

[23][24] Los Angeles County Coroner's Lieutenant Fred Corral ruled the death a suicide, following an autopsy.

"[36][37][38] In June 2016, the group's new rep, Matt Wynter, stated that the girls were back via Loco Talent's website.

Later in October of the same year, Slayton, Estrada and van Oppen started posting TikTok videos with each other, making the rumors of the group reforming increase.

On December 10, 2020, a few clips and pictures from what seemed to look like the set from the group's next music video were posted by Bennett, Estrada and Slayton.

Later in the same month, the group did an Instagram live alongside Antin and Ziedman confirming their return and future new music.

They also explained why Mejia was not invited to said return by saying that Estrada, van Oppen and management were only interested in reforming the group's original line-up.
