What can fans expect this season?
Lea dished on the Do Something Awards red carpet, "Oh my god, there's so much--Kate Hudson... I'm gonna be in New York... you just have to watch it."
Lea added, "It's like a different show. It's really amazing."
She also talked about 10 percent of the show being filmed in New York, so they'll be in New York every two months for a couple of days.
Cory talked about being a celebrity, saying, "It's sad if people get the platform of fame and then don't use it for revealing other causes."
He added that they're "shooting season 4 now. It's incredible, it's very much like two different shows. It's like a show inside of a show."
Cory said he's most excited to "see how the two different worlds interact."
Yeah, we're curious about that too!
Harry Shum said we can expect "what life after high school is" and notes it'll be really interesting with the new talent too.
