Colin Farrell Back On The Market

Irish bad boy Colin Farrell is once again single.

The Hollywood star ended his romance to English writer Emma Forrest after a year.

The couple had begun dating after they were introduced by Martin McDonaugh, who directed In Bruges, the film which earned the Irishman a Golden Globe last month.

An insider told InTouch magazine that Emma felt slighted by Farrell when he failed to thank her during his "Globes" speech.

A source said: 'He would not introduce her to his family. She was also upset that he didn't thank her at the Golden Globe Awards.'

At one point last year, the couple was reportedly planning to start a family and Colin was planning to convert to Judaism, Emma's religion.
