This one might be tough, because presently, there's not too much left of this celeb's original face to reference back to these adorable childhood photos, but see if you can guess who this cutie pie grew up to be.
It's Heidi Blair Montag, that's who!
Estranged mother Darlene Egelhoff posted these images on her blog recently. Such happy memories!
We sincerely hope that she and her mom can work things out! Family is so important!
