Haley and Emily both competed for Higgins' affections on "The Bachelor" Season 20, and later appeared on "Bachelor in Paradise" Season 3 as well as "Ben and Lauren: Happily Ever After?".
"The Twins" series will follow the sisters as they leave their mom's home and pursue life on their own.
"We got our own show, you guys! We don't really know how, but we're very excited," the pair said in a video on their official "Happily Ever After" Twitter.
"Ben and Lauren: Happily Ever After?" was Freeform's highest-rated reality series in three years. Higgins and Bushnell got engaged on "The Bachelor" Season 20 finale, but have yet to set a wedding date.
"2017 I hope is the year that we have huge steps in either getting married or having a really good idea of when we're getting married, but right now we don't," Higgins told E! News last week.
