This star actually honors a talk-radio host named Michael Jackson, not the late King of Pop, who has his own star with a symbol of a record.

In 2015, the "Modern Family" actress' star was desecrated a month after it was installed. Protesters painted the words "Embryo Defense," an apparent reference to a legal dispute between Vergara and her ex-fiance over whether she might destroy two frozen embryos from their relationship.
