Conrad 'very happy' to leave 'The Hills'

Lauren Conrad has said that watching the season finale of The Hills was "bittersweet".

The reality star wrote on her MySpace page that she is ready to move on with some "interesting new projects", which may include writing a novel, People reports.

"A part of me is sad to say good bye to something that has been such a prominent part of my life, but I know that it was my time and I am very happy with my decision," Conrad said of leaving the show.

She added: "While putting my personal relationships and struggles on television wasn't always easy, the support I received from people made such a difference."

She also hinted that the next season of The Hills will "not disappoint".

Last week, Conrad said that she was angry with the series's producers for trying to force her friendship with co-star Heidi Montag.
