Former New York City Mayor Rudy Giuliani is now a paid spokesman for LifeLock.

Giuliani's LifeLock partnership began in November. The Identity theft prevention company LifeLock announced that they would be working with 'America's Mayor' Rudy Giuliani, who will provide "strategic counsel to LifeLock's leadership" and work with "LifeLock to stay ahead of the constantly evolving threat of identity theft."

Giuliani has started to appear in LifeLock television ads, in which he tells customers, "Looking forward to your tax refund? So are identity thieves, and they can steal your identity without you knowing it, in order to get your refund."

"You have to be proactive when it comes to identity theft, especially during tax season." The entire commercial can be found below. 

In an email to ABC News, LifeLock's senior director of corporate communications Tami Nealy said that identity theft has been the number one consumer complaint reported to the FTC for the past 12 years.

She explained that Giuliani "has a strong track record of fighting crime, which is why we are working with him."

Giuliani, since leaving office, has earned a living in a variety of ways. He founded Giuliani Partners in 2002, which has earned millions as consultants to clients (corporations and governments) interested in fighting crime, like Mexico City.

Giuliani hasn't yet responded to ABC News' request for comment or disclosure of the partnership's financial terms.

Although this is Giuliani's first series of television ads, it isn't the first time a politician has turned into a pitchman.

Former Senator Fred Thompson is the spokesman for the American Advisors Group, which is a reverse mortgage company that targets elderly homeowners.

Who could forget Ex-senator Bob Dole's stint as Viagra spokesman, or Mario Cuomo and Ann Richards promoting Doritos?

Even former First Lady Eleanor Roosevelt made a TV commercial for Good Luck Margarine in 1959.

However, some experts question the value of using politicians as pitchmen.

Jordan McAuley, an expert on using celebrities as pitchmen, calls Giuliani an "interesting choice" for LifeLock.

Although the public "liked Giuliani when he was cleaning up New York," McAuley thinks that many people view Giuliani as divisive, or a person who forced policy on the public.

McAuley asked, "Why couldn't they have chosen someone older to go with their demographic? Somebody who everybody likes - what we in the business call a 'Love Boat' celebrity?"
