The "World's Oldest Teenager" has passed away. TV personality and producer Dick Clark died of a massive heart attack this week. The 82-year-old New Year's Rockin' Eve icon had undergone an outpatient procedure at a Los Angeles hospital and suffered a heart attack afterward. He could not be revived. The former American Bandstand host was rife with health problems since suffering a stroke back in 2004. He also had been diagnosed with Type 2 diabetes. Clark got his start in 1956 as the host of Bob Horn's Bandstand, later renamed American Bandstand. In addition to hosting American Bandstand, Clark also hosted Miss USA and Miss Universe pageants during his career, as well as game shows including The Challengers, Scattergories and Pyramid. He also played mentor to American Idol host Ryan Searcrest, who appears to be following in Clark's footsteps. The two had worked together on Dick Clark's New Year's Rockin Eve since 2006. Seacrest Tweeted, "I am deeply saddened by the loss of my dear friend Dick Clark. He has truly been one of the greatest influences in my life." At the beginning of Wednesday night's American Idol, Seacrest started the show by saying, "We can't begin tonight's show without acknowledging the passing of a television pioneer and my dear friend, Dick Clark. Without Dick, a show like this would not exist. He will be missed greatly." The thrice-married media mogul is survived by wife Kari Wigton and three children.
