Thissal, you crack me up.
Caroline looks a great deal like her late grandmother, Charlotte. I see a combination of Rainier and Grace in Caroline
sometimes but Caroline definitely looks like her paternal grandmother.
To me Stephanie looks like Rainier most of the time. She has his eyes and eyebrows. Now, sometimes I will see an expression that reminds me of Grace.
Albert looks like a Kelly/Grimaldi. I can see his mum in his eyes but that's about it. He actually looks a great deal like his paternal grandfather, Prince Pierre....same oval face and tall.
As for Caroline's children w/ Casiraghi, Andrea looks like his father (although I see a little bit of Grace in him) and as we have all said, Charlotte was most appropriately named after her grandmother considering she looks like her mum and in turn her mum like grandmum Charlotte. Pierre looks like a Casiraghi to me and Alexandra looks like Ernst, IMHO.
Stephanie's Pauline looks like her mummy; Louis looks a bit like Albert and Camille looks like Stephanie and Grace. She is really the only grandchild, apart from Andrea, who got some of the Kelly genes...at least to me.
