Too. Stinkin. Cute.
By the way, there's no such thing as a Lionhead-dwarf mix
. "Dwarf" isn't actually a breed, it's a gene that is found in a variety of breeds. It's an odd gene - one copy = dwarf-sized rabbit but two copies = peanut, a fatal flaw that causes an exceptionally small baby that dies very early on. Because of this, many breeders of dwarf breeds breed one parent who has a copy of the gene with one that doesn't. This way, half the babies are true dwarves (have a copy) and half are just normal (larger than breed standards). If both parents have a copy, then you get 25% 'normal', 50% 'dwarf' and 25% peanuts. I have a lionhead and a holland lop, both of whom are dwarves... however, my first holland lop was NOT a true dwarf - she didn't have a copy of the gene and weighed too much to meet the showing guidelines for her breed.
Lady Bun looks like a purebred lionhead (and if she's anything like mine, probably sweet and smart but also feisty as hell, hehe). Do you know how old she is? If she's past about the 6-8 month mark, the thick mane and "skirt" of longer fur on her hips suggests she's double-maned (2 copies of the mane gene)... if younger, then when she blows her juvenile coat, she may or may not retain these characteristics (my Nala is single-maned and, as an adult, has a much thinner mane and no skirt). If she weighs 3.5 lbs or less as an adult then she's got the dwarf gene, otherwise she's a 'false dwarf' (meaning a dwarf-breed rabbit without the actual dwarf gene).
