Nearly everything Ryan Seacrest touches turns to gold -- including the iHeart Radio Music Festival which he’s hosting this weekend for the 4th year in a row.

“Well I’d like to take credit for this but there are a lot of people,” Seacrest said.

FoxNews.com caught up with Seacrest backstage at this weekends’ star-studded iHeart festival, where acts like Taylor Swift, Nicki Minaj, Coldplay and Ariana Grande are performing.

“What I love is that every year this goes by it gets bigger and the artists are even more and more enthusiastic about it,” Seacrest said. “Now they can’t wait to get here and figure out what kind of signature move they’re going to leave.”

The iHeart show is only four years old but is already Vegas’ biggest music festival.

Dozens of the hottest names in radio and entertainment descend upon Sin City for the highly anticipated weekend. Forbes reported the average cost for a ticket this year is about $700.

“It’s all-star,” Seacrest said. “I mean when you watch the screen, every single person is a main headlining act.”

Of course you can’t talk to Seacrest without chatting about "American Idol." He said so far he’s seen the best talent come from this year’s auditions in the Big Apple.

“We’ve seen all walks of artistry but in New York believe it or not we’ve had one of the strongest turn-outs,” Seacrest said. “We’ve been there often and sometimes it’s hit-or-miss but we saw some really great talent in New York last week so I’m excited to see what they do.”

Seacrest also talked about "American Idol" alum Adam Lambert -- who made history this week as the first former-contestant to fill in on the judges’ panel during auditions in New York.

“He was brilliant. He sat in there. He had some great insight for the contestants. He was one so he had that perspective,” Seacrest said.
