Canadian journalist Rebecca Eckler is suing Universal Studios over their latest hit movie Knocked Up, claiming the film was inspired by her best-selling book.

Eckler's 2004 novel "Knocked Up: Confessions Of A Hip Mother-To-Be" detailed the party-loving journalist's unplanned pregnancy and subsequent birth of her daughter Rowan.

In the latest issue of Maclean's magazine, Eckler accuses the makers of the movie of stealing the premise from her novel and says she plans to take legal action.

She says, "Both my book and the movie feature one night of passion and the nine months that follow. Fine. Whatever. But what got me was the fact that Alison (Katherine Heigl) was an up-and-coming television reporter; in my book, I was an up-and-coming newspaper reporter."

Heigl plays a TV journalist who falls pregnant with unemployed Seth Rogen's child after a one night stand.
