The 32-year-old 'Got To Dance' judge, who is due in December, revealed the couple are planning to bring the child in England, reported Hello magazine.
"I love the life Max and I have built here. England is home for me now. There is nothing cuter than having a baby growing up with a British accent," said Wyatt.
The singer said her former Pussycat Dolls bandmate Ashley Roberts guessed that she was pregnant.
"Ashley knew straight away. We are like sisters. Ashley knows everything about me, so she only looked at me and guessed right away. When I told her, it was so emotional, she was thrilled for us, which was lovely," she said.
