Erica Rose has become a first-time mom.
Rose told E! News she is "feeling good and still recovering" after delivering via C-section.
She and Gentry named the infant after her late aunt and Gentry's late mom, who died earlier this month.
"We are so happy to welcome Holland Rose Madeleine Gentry into the world," the former reality star told "Entertainment Tonight."
"We added the middle name Madeleine because Galen's mom just passed away in the last two weeks," she revealed.
"We named her Holland after my late aunt Holly and a nod to Galen's Dutch ancestry."
She had announced she and Gentry were engaged and expecting in February.
"She is super excited about the baby," a source told People magazine at the time.
"She's so happy to have found a good guy to share this journey with her."
