Former "Tonight Show" sidekick Ed McMahon can now add rapping to his broad entertainment experience! ET spent the day with Ed as he took to the streets of Hollywood decked out in hip hop gear and full-on bling to rap for a new Internet video campaign.

McMahon, 85, was tapped by FreeCreditReport.com to star in the viral videos for the company amid his own financial woes.

Ed tells us he even surprised himself by being able to rap in the videos, which also feature him escorting some sexy ladies down the street and showing off an expensive mob-style suit.

Tune in to ET on Friday to see behind-the-scenes footage from the video shoot as well as Kevin Frazier's interivew with Ed in which he discusses his improving health and housing problems.
