Singer/actress Mandy Moore and Nicole Richie's ex-fiance DJ AM are dating. Moore, 22 and DJ AM - real name Adam Goldstein - have known each other for years, but only started spending more time together after meeting at a New Year's Eve (31DEC06) party in Miami, Florida. A source tells American publication People, "It's really new. They're in the beginning stages of getting to know each other. They're very into each other. It's very sweet." Moore was also spotted on New Year's Eve getting close to her ex-boyfriend Wilmer Valderrama, sparking reports of a reconciliation, but since arriving back in Los Angeles she has been spending time with Goldstein. Moore split with SCRUBS star Zach Braff last year (06), while Goldstein split with Richie in December 2005.
