Kim Zolciak, formerly of Real Housewives of Atlanta, and her husband Kroy Biermann announced on Monday that Zolciak had given birth to twins, a boy and girl.

According to the Los Angeles Times, they announced the news via Instagram.

She wrote that "We are officially the 'Biermann Bunch' now!" The picture was a note that read: "Guess what?!!! The TWINS have arrived! We welcomed first a baby GIRL and second a handsome little BOY. They are both healthy, and Kroy and I are so thankful!!"

They also posted the names of their two new additions, Kaia Rose and Kane Ren. The reality TV personality also provided her Instagram followers with the reasons for their two names. Kaia Rose is named "After 'Psychic' Rose who is like a grandma to me and been a huge part of my life for 13 plus yrs."

Her new son has been fated with the name of the OBGYN who has delivered all but one of her kids and unsurprisingly has "been a big part" of her life.

Throughout her pregnancy with her twins, Zolciak has kept fans aware of everything that has gone on, New York Daily News notes.

After she first announced the news, just months after giving birth to Kash Kade, people wondered about her pregnancies and she responded, "It was a natural conception, but twins do run in my family, so I guess I shouldn't have been surprised.

The Times notes that Kaia Rose and Kane Ren joins several other kids, including 16-year-old Brielle, Ariana, Kroy Jr. and Kash Kade.
