The reality star, who divorced Chad "Ochocinco" Johnson in 2012, is six months along. She is keeping the identity of the baby's father a secret.
"I'm excited about being a mommy all over again," Lozada said. "This is something I've been wanting for years and I can't believe it's finally happening."
Lozada, 37, has a daughter, Shaniece, 20, from a previous relationship.
