Heigl salary stories 'ludicrous'

A spokesperson for Katherine Heigl has lashed out at reports she was dropped from an upcoming A-list movie ensemble due to her extortionate salary demands.

The 'Grey's Anatomy' star, who broke into movies with 2007 comedy hit 'Knocked Up', was expected to join Hollywood superstars Julia Roberts, Jennifer Garner and Anne Hathaway in romantic comedy 'Valentine's Day', due to hit screens in 2011.
