DJ AM and Mandy Moore dated for only two months in 2007, but since his plane crash last month, "It's back on," a source close to AM tells Us Weekly.
"Since the accident, it's blossomed into something again."
Mandy Moore rushed to DJ AM’s side after the September 19 crash that left him with burns on his arm and face, injured Travis Barker and killed four others.
Added the insider, "Mandy said, 'I like this guy a lot and I want to see where it can go again. Life is too short to not be with someone you really care about.'"
A witness who saw them at the October 18 Friendly House event in Beverly Hills says, "He was holding her hand, and they were rubbing each other's backs."
So after romances with other celebrities - DJ AM, 35, was once engaged to Nicole Richie, 27, while Moore went out with Scrubs star Zach Braff, 33, and tennis pro Andy Roddick, 26 — can the reunited couple make it work this time?
Says a DJ AM pal, "When you go through what Adam went through, you need people you love and people who love you. He will never stop loving her."
