DJ AM & Mandy Moore: Lovers' Reunion

Since resuming their romance last month, DJ AM (Adam Goldstein) and Mandy Moore have been making beautiful music together. The duo is collaborating on Mandy's upcoming album.

"Mandy has always loved Adam," a pal of the couple tells OK!. "She's always thought he was brilliant when it came to beats and music."

AM has even offered to remix several of the singer's tracks to make them more "club friendly." Needless to say, Mandy, 24, and AM, 35, have had plenty of late night sessions. "They are falling back in love, fast," the pal says.

Mandy most recently dated rocker Ryan Adams and previously dated tennis pro Andy Roddick. AM was once engaged to Nicole Richie.

"When you go through what Adam went through, you need people you love and people who love you," a source said. "He will never stop loving her."
