Celebrities from the world of music, media and politics took to Twitter in droves to pay tribute to Dick Clark, who died Wednesday of a heart attack at age 82.
"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," tweeted Ryan Seacrest. "My thoughts and prayers are with his family."
The "American Idol" host had worked closely with Clark on "New Year's Rockin' Eve." Seacrest told The Los Angeles Times after his death that he had "idolized him from the start" and was "graced early on in my career with his generous advice and counsel."

Later Wednesday, Seacrest honored Clark on "Idol" by saying, "without Dick, a show like this would not exist."
"I know this guy – he's in a better place, saying, 'Hey, let's get on with the show, okay?' " Seacrest said. "You got it, boss."
Madonna led her website Wednesday with a video clip of her 1984 appearance on his show where she talked about wanting to "rule the world."
News of Clark's death also prompted a reaction from the White House. President Barack Obama said in a statement that he and first lady Michelle Obama were "saddened to hear about the passing of Dick Clark."
"With 'American Bandstand,' he introduced decades' worth of viewers to the music of our times," Obama said. "He reshaped the television landscape forever as a creative and innovative producer. And, of course, for 40 years, we welcomed him into our homes to ring in the New Year."
"But more important than his groundbreaking achievements was the way he made us feel — as young and vibrant and optimistic as he was. As we say a final 'so long' to Dick Clark, America's oldest teenager, our thoughts and prayers are with his family and friends — which number far more than he knew,"
