-Colin & Britney To Have Affair Spilled in Book?!?

A California model is suing actor Colin Farrell, claiming he sent her sleazy text messages.

Dessarae Bradford, a former sex chat-line worker, said Farrell also stalked her after a short courtship, the London Sun reported Sunday.

And Bradford says she plans to write a book about the "Alexander" star called "A Dark Twisted Puppy," hinting it would include tidbits of his alleged affairs with Britney Spears, Angelina Jolie, Paris Hilton and other celebs.

In court documents, Bradford says she suffered "mental anguish" and was "degraded" by the actions of Farrell, 28.

She is suing him for "breach of contract, return of erotic tape and art, cost of dress, shoes and accessories," the documents said.

Her small-claims lawsuit in Santa Monica, Calif., seeking $4,600 is to be heard Feb. 16.
