Nick Lachey dated Kim Kardashian in 2006 for a few days, and she has credited that short-lived romance as contributing to her rise to stardom in her book Kardashian Konfidential.
When Lachey was asked about it, he said that she alerted paparazzi that they were on a date so she could be photographed with him.
In an interview with Details magazine, he said they went on a date to the movies.
"Let's just say this: we went to a movie," he said, "No one followed us there. Somehow, mysteriously, when we left, there were 30 photographers waiting outside. There are certain ways to play this game, and some people play it well."
He also said that the sex tape was "already in the can" at that point.
