Calvin Harris: Done Dating Celebrities

Calvin Harris is DONE dating famous chicks, and blames his terrible experience with Taylor Swift for the change of heart.

Sources close to the DJ tell TMZ ... Calvin believes celebs are narcissistic, and all he wants is a normal girl.

As for his type ... he's very, very clear -- sexy latina ... a Sofia Vergara-type who is not famous.

As for why Calvin thinks Taylor's a narcissist ... he can't believe she dumped him when he was down after his car accident ... just because she found a shiny new object. He also says she was so obsessed with her life and career she felt put out whenever he had plans that conflicted with what she wanted him to do.

We're told Calvin doesn't want back in a relationship anytime soon, and he shouldn't have much of a problem ... as the resident DJ at the biggest nightclub in Vegas.

As for reports he hooked up with Megan Rees ... we're told Calvin laughed at the stories and says it's BS.
