That's just gorgeous!! Are those balls truffles/cake pops?

Yes, cake balls :)

so for the pink tier...is that actual cake?  I've done several cake ball cakes but I've never stacked a cake ball cake on a "real" cake.....I was afraid of the weight.  its beautiful

Thank you!  The bottom three tiers are dummy cakes covered in fondant and decorated.  The top tier is an actual cake.
