“I think that it’s very sobering being here today and I have a lot of empathy with people who lost family and lost partners in that tragedy,” she said Sunday from the front row of a New York Fashion Week show for Edun.

“A huge part of being human is losing people; for these people who lost someone it’s especially more painful because it didn’t need to happen. I was thinking about that today, ‘How does that complicate their grief?’“

Rae, 32, was among a pack of celebrities who turned out to support the label founded by U2’s Bono and his wife, Ali Hewson.

Bono bandmate The Edge, Sting, models Naomi Campbell and Christy Turlington, and Courtney Love also sat on the front row.

Grammy-nominated Rae said she’s been able to move on since her husband’s 2008 death and hopes for the same peace of mind for those affected by Sept. 11.

“I hope that the way in which they lost people hasn’t stopped them from processing what’s happened and moving forward and having new things develop in their lives,” she said.
