Christine McGuinness' children Leo, Penelope and Felicity
Paddy McGuinness' wife Christine shared the most heartwarming post alongside a photo of her three children dressed up for World Book day.
She said: "My heart just smiled. This morning I have a very happy ‘Jessie’ from toy story, a beautiful ‘Snow white’ and fabulous ‘Super Mario’ for #WorldBookDay. ⠀
"I remember when my children would never dress up because the costumes were too itchy, (I still have to put soft layers underneath) but they wouldn’t even touch the fabric! And just seeing other children wearing costumes would totally confuse and upset them. Now they understand, we prepare and they enjoy World book day."
Kate Ferdinand's son Cree
Just how cute does Kate and Rio Ferdinand's one-year-old son Cree look in his mini Woody costume with big sister Tia?! We're obsessed.
Kate wrote: "You’ve got a friend in me [heart emoji]… World Book Day."
