celebrytce

In a sentence

• Podziwialiśmy strój, który celebrytce doskonale pasował.

  We admired the outfit that suited the celebrity well.

  This usage of 'celebrytce' is the dative form of the word 'celebrytka' which means 'a female celebrity'. It is used here to indicate that the action (admiring the outfit) relates to the celebrity.

• Kupiliśmy prezent celebrytce na urodziny.

  We bought the celebrity a present for her birthday.

  Again, 'celebrytce' is in the dative case, indicating the recipient of the present (the female celebrity).

• Rozmawialiśmy z celebrytce o jej najnowszym projekcie.

  We talked with the celebrity about her latest project.

  Here, 'z celebrytce' seems incorrect; to properly indicate talking with the celebrity, the phrase should be 'z celebrytką'. The correct usage involves the instrumental case for such context.
