The E! host and her husband Bill Rancic are currently expecting their first child together via a gestational surrogate.
Rancic has now told Us Weekly that she has been asking for advice from Kris Jenner, the mother of Kim, Kourtney, Khloe and Rob Kardashian and Kylie and Kendall Jenner.
"Kris Jenner is like my second mother," Rancic confessed. "Kris gives me the greatest advice. You'll email her one question, one line, and she'll respond in four paragraphs. She's the most thorough, amazing woman."
Rancic, who described Jenner as "amazing", also revealed that she "sent the best gifts for the baby" including Ralph Lauren Olympic polos.
Bill Rancic recently admitted that he and Giuliana are in "rush mode" as they prepare for the arrival of their son.
