Whoa, mama!

Kim Zolciak and her husband Kroy Biermann welcomed their newborn twins, she announced Monday. And guess what? The couple are now the proud parents of a boy—and a girl!

"We welcomed first a baby girl and second a handsome little boy!" she wrote on Instagram. "They are both healthy and Kroy and I are so thankful!!

Kim has been eagerly awaiting this day. Over the last nine months, she's been happily showing off pictures of her budding baby bump.

Upon finding out she was giving birth to twins, she revealed this summer, "I was completely shocked. I had no idea. It was natural conception, but twins do run in the family, so I guess I shouldn't have been surprised. I can't believe I am going to be a mom to six children…it's going to be very busy but it's a dream come true!"

Kim and Kroy are now doting parents to six children: Brielle, 16; Ariana, 12; Kroy, 2; Kash, 1; and now, their two newborns.
