Hollywood couple Renee Zellweger and Bradley Cooper have been spotted house hunting together in Los Angeles. They started dating in summer 2009 and Cooper introduced Zellweger to his parents in September this year, reports hollywood.com.

"Until Renee, Bradley had a reputation as a ladies' man and a heart-breaker, but he seems so happy with her. They prefer to stay in rather than hanging out at parties and he has already introduced her to his parents," said a source.

Cooper has previously dated Jennifer Aniston and Cameron Diaz, while Zellweger was briefly married to country singer Kenny Chesney.
