Here Comes Honey Boo Boo star Anna "Chickadee" Cardwell is a mommy once again!

The 21-year-old reality star recently gave birth to a baby girl named Kylee Madison Cardwell. While the little bundle of joy is Anna's second child (she has a 3-year-old daughter, Kaitlyn Elizabeth Clark, from a previous relationship), this is her first with husband Michael Cardwell, whom she married in 2014.

Last week, ET spoke to Anna's mother, Mama June Shannon, who told us that the newborn is not named after Kylie Jenner and that the middle name is after the paternal grandmother.

Anna herself is one of four, as the oldest of Mama June's children, which include Jessica "Chubbs" Shannon, 18, Lauryn "Pumpkin" Shannon, 15, and Alana "Honey Boo Boo" Thompson, 10.

The family became famous on TLC's reality show, Here Comes Honey Boo Boo, but after the network canceled the series due to Mama June's reported rekindled relationship with a convicted sex offender, which she denied, Anna sued her mother for allegedly keeping $300,000 in profits from the show that was owed to her and her daughter, Kaitlyn.

"I talked to her before I came out here," Mama June said. "We thought we were going to have the baby Sunday before I came out here. She called me and she's actually supposed to be going to the doctor today and next Tuesday she'll be having Kylee."
