Us Weekly has learned exclusively that after two months of dating Nicole Richie and Brody Jenner have called it quits.

Richie's rep Nicole Perna confirms the break-up exclusively to Us, saying: "Nicole and Brody are no longer dating but remain close friends."

A source says that Richie initiated the breakup today at Jenner's home in Malibu and that both Jenner, 23, and Richie, 25, agreed it was best to part ways.

"Nicole just wants to be single right now," says the source. "She felt it was a mistake to jump into a relationship so soon after her breakup with AM."

Richie and Adam "DJ AM" Goldstein split in May of this year after a nine-month engagement.
