The mum-of-five revealed that Molly, 13, and 11-year-old Lilly - her daughters with former Westlife singer Brian McFadden - will be in Ireland with their dad visiting their nan.
Kerry told OK! Magazine: "When we're not all together, it doesn't feel whole. I'll be shedding a few tears waking up without them this Christmas."
But despite her heartache, the reality TV and Atomic Kitten star will have more than a houseful to keep her company on Christmas Day.
As she prepares for baby Dylan-Jorge's first Christmas with new husband George Kay, Kerry said: "I'm so excited! I looked like a Christmas pudding this time last year. We were going to go to Cape Verde for Christmas this year but we decided to stay at home and I'm so pleased."
The couple are planning to spend the festive period with her mum, George's parents and Heidi, seven, Max, six (Kerry's children by Mark Croft), and nine-month-old DJ.
In the interview, she was also keen to dispel rumours that her marriage is on the rocks.
She said: "My words were completely twisted – all I was trying to say was that you can never be 100 per cent know the future in life for certain. But I'm happier than ever.
"I could just never see myself without George. He's my bestest mate in the whole world."
