Alongside two pictures of herself with her three children, she wrote: "Celebrating Sailor. She's 23. Hates being told she looks like me, an adventurer with bruises on her knees, all the puppies love her and she lives with three, never brags she does things secretly.

"She can climb really fast to the top of a tree, and ski down a mountain faster than me, she's as sweet as honey from the honey bee, a passionate supporter of causes hum-b-ly."

She continued: "When she raps and dances, it's something to see and that's a little something about my 3rd baby. Happy Birthday Sailor Lee @sailorbrinkleycook @alexarayjoel @jackbrinkleycook."
