The 34-year-old reality star, who already has three young kids Harvey, 11, Junior, 8, and Princess, 6, said she is nervous about her pregnancy, reported Sun online.
"We're all over the moon. I'd be lying if I said I wasn't nervous because I've experienced miscarriages in the past," she said.
Price, 34, and Hayler, 25, whose first child will arrive towards the end of the summer, have been inseparable since a whirlwind Christmas romance which ended in a beach marriage in the Bahamas last month.
