"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!!
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.
