Rachel, a 25-year-old flight instructor from Clermont, FL, and Gabby, a 30-year-old ICU nurse and former NFL cheerleader from Denver, CO -- who both had their hearts broken by Clayton Echard on The Bachelor's 26th season -- will co-star on the series.
Former The Bachelor star and sports commentator Jesse Palmer, who just hosted Clayton's season, will be returning as host for The Bachelorette.
Cast and format details about the new season have yet to be released, and Gabby, Rachel and Jesse all have said they are unclear how the show will work with two Bachelorettes.
Given The Bachelorette season won't premiere until mid-July, it remains unclear if ABC will also air a season of Bachelor in Paradise -- which normally begins airing in August, right after The Bachelorette concludes -- this summer.
During The Bachelor's Season 26 finale on Tuesday night, viewers watched Clayton break up with and devastate Gabby and Rachel -- in a group dumping session -- after having sex and professing his love to both of them in order to chase down the girl he was "most in love" with, Susie Evans, who became his girlfriend in the real world once filming ending.
Jesse announced at the end of the live finale broadcast how both Gabby and Rachel will star on The Bachelorettenext season after enduring a tumultuous and emotional ride on Clayton's season.
"We beat ourselves up trying to make this decision. It took weeks and weeks," Jesse shared once Gabby and Rachel joined him onstage in the Los Angeles studio during the live finale.
"But at the end of the day, watching you both support each other in Iceland, and also how you have tonight, that's really the big reason why we decided to give you both a shot. You truly are deserving of this. This is going to be amazing -- this is your journeys!"
For the first time ever, The Bachelorette will have two leading ladies for the entire season.
The reality dating series featured two Bachelorettes once before on Season 11, but the men voted for their favorite of the two women at the end of Night 1 and ultimately selected Kaitlyn Bristowe to continue on the show instead of Britt Nilsson.
When asked what they're looking for in a perfect man, Rachel shared with Jesse on Tuesday night how she'd like a supportive man and someone who actually loves her, which was clearly a jab at Clayton.
And Gabby told Jesse, "Someone who's emotionally intelligent, mature, who can challenge me, and... [a sense of humor]."
Gabby and Rachel have also gushed about how they're excited and grateful to be given this opportunity together, as a team.
