Breaking up is never easy, but for Nicole Richie, seeing her ex-boyfriend at an LA event with his new girlfriend is almost a Hollywood nightmare.
The socialite, who ended her three-month long relationship with childhood friend Brody Jenner only weeks ago, was brought to tears when he arrived at a party she was at with his new love.
Jenner, who starred on the reality TV show Princes of Malibu, arrived at an LA fashion week event with Lauren 'LC' Conrad, who made a name for herself on the MTV show Laguna Beach.
Richie, who recently rekindled her friendship with Paris Hilton, was visible upset by the sighting so soon after their break-up.
"Nic is furious," a source told Life and Style magazine.
"She said: 'LC just keeps saying hi to me over and over again. I can't stand it! It's like she's rubbing it in my face. Just leave me alone!'"
However the super skinny star soon found solace with ex-fiance DJ AM, as she reportedly spent time in his DJ booth.
"Nic went up to his booth and got a big hug," the source said.
"They whispered to each other, and DJ AM was able to turn her night around."
