Actress Kate Hudson has taken a swipe at Hollywood rival Katherine Heigl, by pretending she has never heard of the Knocked Up star.

Heigl is the biggest new star of the past year, thanks to roles in the pregnancy comedy, romantic movie 27 Dresses as well as her ongoing part in the hospital drama series Grey's Anatomy. But, when asked what she thought of the bright new star, Oscar-nominee Hudson feigned ignorance.

She told Elle magazine, "Who is she?... Oh, that girl in 27 Dresses? I just don't think about that stuff."
