He's the host of "American Idol" and the voice behind "American Top 40, "but that's just scratching the surface of Ryan Seacrest's portfolio.
When he's not behind the mic or in front of the camera, Seacrest sometimes plays foil to some of Hollywood's biggest names. This week it's Nicole Richie as she finds out what's like to co-host with one of the biggest personalities in America.
"He has like 19 jobs so I just want to see ... is he on something?" said Richie. "Do highlights give you more energy? I'm going to find out."
Richie may have discovered that he's a man of many talents. But here are 10 things she may not have known about Hollywood's jack-of-all-trades.
Seacrest was vacationing in Mexico back in 2008 when a sand shark inched up and bit his toe before swimming away. Seacrest told E! he popped an Aspirin and walked it off.
Before he made it big with "American Idol", Seacrest hosted several game shows including "Wild Animal Games", "Click" and our favourite: "Gladiator 2000", featuring a 20-year-old Seacrest in a t-shirt and basketball jersey.
You wouldn't believe it based on his current photos but Seacrest struggled with weight problems. He told Men's Fitness that his childhood obesity now serves as a source of motivation to live a healthy lifestyle as an adult.
It's called Katana and it serves up Asian fusion in the heart of Hollywood.
The show zeroed in on America's obesity epidemic and brought in Britain's Jaime Oliver to revolutionize one city's eating habits.
Since the launch of Ryan Seacrest Productions in 2006, Seacrest has produced shows like "Keeping Up with the Kardashians", "Kourtney and Kim Take New York" and "Kourtney and Khloe Take Miami".
His radio show isn't the only thing with his name on it. Back in 2010, Seacrest, along with his family started the Ryan Seacrest Foundation, a charity aimed at enhancing the lives of kids in need.
She's back! Nicole Richie returns for her second season of Candidly Nicole and she brought back her humour and outspoken perspective.
