Nick Lachey opened up recently about his short-lived relationship with Kim Kardashian and suggests that she used him to get famous.

In 2006, the former 98 Degrees singer briefly dated the then relatively unknown Kardashian following his divorce from Jessica Simpson.

In Details magazine, Lachey was asked if Kardashian tipped off the paparazzi when they went on a movie date.

“That’s one way to interpret it. Let’s just say this: We went to a movie. 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 continued.

In her book, “Kardashian Konfidential,” Kardashian claims that her fame rose after her date with Lachey.

“It started when I went out on a date with Nick Lachey. Of course, the paparazzi took pictures, because people were curious about who he was with.

"So the next night I was out with Paris Hilton, we were in her car, and the paparazzi started taking pictures. Usually they would shout, "Paris! Paris! Paris! [But] they started yelling "Kim! Kim! Kim!" I wanted to hide, and Paris and I just looked at each other and laughed,” she continued.

“She said, ‘Whatever you do, just smile.’ I thought, this is so weird, I don't know what’s going on. It was surreal.”

Meanwhile, Kardashian is currently dating rapper Kanye West. She is pregnant with their first child and is due to give birth in July. She is also in a bitter divorce with NBA basketball star Kris Humphries.

Lachey is married to television personality Vanessa Minnillo, and they have a baby boy named Camden.
