Jessica, who is mum to daughter Maxwell and son Ace Knute with fiancé Eric Johnson, wrote a sweet message about her kids and shared it with fans last night (6 March).
Jessica first posted a snap of Maxwell, in which the tot is seen staring into the distance.
Wearing a striped white and pink top, Maxwell looks too cute as her blonde curly hair frames her face. Captioning the photo, 33-year-old Jessica said: "The most beautiful girl in the world."
'Irresistible' singer Jessica then cuddled up to Ace, who was wearing a whale print all-in-one suit.
Writing a similar message, devoted mum Jessica said: "The most handsome boy in the world." Aww!
Last week, Jessica also shared some super cute photos of herself and Maxwell playing dress-up with identical oversized sunglasses!
