Paris Hilton Was Awful Partying Influence, Ex-Boyfriend Nick Carter Says

Paris Hilton was a terrible influence when it came to substance abuse, according to her ex-boyfriend Nick Carter.

“Paris was the worst person in the world for me to hook up with," Nick says of the fast-living socialite in excerpts from his new memoir, Facing the Music and Living to Talk About It, released to In Touch.

The former Backstreet Boy, now 33, said that Paris, who was famously caught with cocaine three years ago, "fed my worst impulses as far as partying” during the time they dated between 2003 and 2004.

“I could’ve ended up a tragedy,” Carter said, noting that "during the height of my problems, I did Ecstasy, cocaine and drank a large bottle of vodka a night."

Carter, who's been sober the past five years after a decade of decadence, said his biggest regret over past drug abuse involves Ecstasy.

“The amount I did caused changes to my brain that are responsible for my bouts of depression now,” he admitted.
