The glamour model's sister Sophie uploaded a snap of the 2-year-old wearing lip gloss, eye shadow and the stick-on lashes on her Facebook page this week.
'She's a 2-year-old girl with make-up for the whole world to see,' said Pete on GMTV today.
The 36-year-old thinks Princess is too young to be covered in cosmetics.
'Peter totally disagrees with anything like this,' his spokesman tells The Sun.
'He has said in the past he hates Kate colouring Junior's hair and straightening Princess's.'
But 31-year-old Jordan's family have played down the photo.
'How sad that my sister can't even play dress up with Princess like all mums and daughters do,' Sophie, 20, tells the Daily Star.
Jordan tied the knot with Celebrity Big Brother winner Alex Reid, 34, in Las Vegas last week.
