Justin Timberlake has a few tricks up his sleeve going into this weekend's [article id="1710531"]iHeartRadio Music Festival[/article]. And some of the rabbits he's pulling out of his top hat are unreleased tracks off [article id="1712379"]The 20/20 Experience - 2 of 2[/article] out September 30.

"It's gonna be fun to play this year. Well I have not put the set list together yet because, as you know, I procrastinate on things like that. We're looking at playing some new material from the second half of this record," the "Take Back The Night" singer said of the follow-up to March's The 20/20 Experience in an interview with Ryan Seacrest on Thursday.

Timberlake has already teased to MTV News that the [article id="1713148"]second half will be the "more dangerous"[/article] older sister, saying, "The first half the sun is out the second half the moon is out, I don't know."

In addition to new music, Timberlake will soon hit the big screen in "Runner Runner" alongside Batman himself, Ben Affleck.

"It's an exciting movie it's a lot of fun too. I got excited when I first read the script because it reminded me of a certain genre of thriller that you and I probably grew up with," he said of the film, which hits theaters on October 4. "The characters are really intelligent. It just felt like a nice little twist but also an homage to the thrillers that I love growing up. And then Ben Affleck signed on. We had a lot of fun shooting it. It's smart and it's got a lot in it."

The same day he appeared on Seacrest's radio show, the "Today" show teased a part of their upcoming interview with the pop star, where he weighs in on Miley Cyrus' headline-making VMA performance, which he previously likened to [article id="1713189"]performances from Britney Spears and Madonna[/article].

"I don't know that I have definitive thought in one direction or the other about it. I think she's really smart, and I think she's really talented. I'm not saying I agree with the presentation, but I also feel like every 10 to 15 years we pick somebody that this is what we're going to do with them — that were going to make them the model of who we want our daughters to be or not be" he said. More of the interview will air next week on "Today."

As for Miley, she'll give her own take on the August 25 performance during her MTV documentary "Miley: The Movement," airing October 2.
