"Happy Birthday my darling Lauren, you have made our lives so wonderful because you are so special." Patti wrote.
"You are loved by everyone."
The sweet tribute garnered likes from many famous faces including Home & Away's Georgie Parker and My Kitchen Rules star Ash Pollard.
Rhonda Burchmore even voiced her support in the comments, writing, "Happiest birthday beautiful Lauren."
Other fans were also touched by the performer's post, flooding Patti's comments with birthday wishes.
"She had a very difficult pregnancy and she went into hospital, and was there for three months," Patti told the publication.
"To make everything easier, Bert and I got permission (during COVID restrictions) from the doctors to look after the little ones."
Bert Newton himself also recently spent some time in hospital after a frightening health scare.
In November last year, Patti shared a snap from Bert's hospital bedside. The TV legend was sporting a hospital cap and gown.
“Bert’s been in hospital, all good,” Patti captioned the photo “‘He’s Got a Lot of Living to Do.’”
The presenter managed to return home in time for Christmas to spend the holiday with his loving, and ever-growing, family.
