Hatla Williams?
Don't know if she is calling herself that only for 'phonetic'
purposes...
her name is Halla Vilhjálmsdóttir or just Halla Vilhjálms.
That Hatla stuff...it's stupid.
It is possible that is simply misspelled. This has happened already more than once.
June 29th. I gotta get i shape now...
Maybe for more worldwide appeal.
In Iceland she prob would have stuck with Halla Vilhjálmsdóttir (Daughter or Vilhajlm/William)
