Spot the Sisters #1 - Can You Tell Who's Who?

Since I have received comments that my girls look alike and the hubby and I have an internal contest of who can best tell their childhood pics apart, I decided to hold a Spot the Sisters challenge for him, for the family, for some friends and for whoever wishes to participate!
If you have been a faithful reader of A Happy Mum, do try this out too for the fun of it!
It's simple, just determine which pics are Angel and which are of Ariel. Hint: Half belong to each of them. Comment away and I will reveal the answers next week!

To the hubby, are you seeing stars already? Tsk tsk.
