Steve Martin tweets from "jury duty"

Steve Martin has posted a series of jokes on Twitter while supposedly on jury duty.

The comedian began posting regular updates under the tagline "REPORT FROM JURY DUTY (sic)" on Monday, causing a large number of concerned followers to point out that the actor's comments could land him in trouble.

On Monday, Martin wrote: "REPORT FROM JURY DUTY: defendant looks like a murderer. GUILTY. Waiting for opening remarks," before adding: "REPORT FROM JURY DUTY: guy I thought was up for murder turns out to be defence attorney. I bet he murdered someone anyway."

Later posts included: "REPORT FROM JURY DUTY: Prosecuting attorney. Don't like his accent. Serbian? Going with INNOCENT. We're five minutes in," as well as: "REPORT FROM JURY DUTY: Now forcing my autograph on other jurors. Also starting whisper campaign of innocence based on Magic 8 Ball."

Martin's spokesperson confirmed to Reuters that the star is indeed on jury duty at an unnamed court, but that he is still awaiting selection and that his comments are not based on a real trial.

"He is not actually tweeting during a trial but is on jury duty," the rep said. "He's making jokes that are really funny - nothing actually factual though."

The spokesperson also revealed that Martin has not yet been "kicked out" of the jury pool.
