She has also forced her to swear off sex for a year, saying men distract her focus."The two friends have been spotted out together regularly in the past year - after having became close after the death of Gwyneth's TV producer father Bruce Paltrow in October 2002 - and Gwyneth, 40, previously hoped to find the perfect man for her bubbly pal.A source explained: "Gwyneth is a nurturer. Cameron is bummed about being single, so Gwyneth sees her as a project. She's trying to set her up with guys!"Cameron has previously dated several famous men, including Justin Timberlake, baseball player Alex Rodriguez and Jared Leto.
