Mariah Carey has a very close relationship with her fans, who she refers to as “lambs” or, lately, “The Lambily.”  Now, she’s going all out by planning an entire day in their honour.  Mariah has announced … Lamb Appreciation Day, which will be on February 11 — a date, according to her website, whose symbolism “only Mariah fans can understand.”  So far, Mariah hasn’t revealed any details about the day except to say that she’ll be “participating in many fun activities” with her fans online, including “sharing home videos, talking about her favorite songs and answering fan questions.”  “Special giveaways” and “many surprises” are also promised.
