"X Factor" boss Simon Cowell sat down with Ellen DeGeneres on her talk show on Tuesday (September 10) to talk about lots of things, including opening up about his impending fatherhood and explaining why his experiment with Britney Spears on "Factor" was a bust.

You might recall the hype that surrounded the addition of Spears to the "Factor" panel last year. "There was a time where I think everybody was trying to up themselves in terms of who could find the biggest known star to be on a panel," Cowell said, naming "American Idol" judge Jennifer Lopez and the "other one ... blondie" on "The Voice," in reference to Christina Aguilera.

"And so we thought, 'well, we'll take Britney. And she was fine, but I think she found it very uncomfortable," he said, perhaps explaining Spears' GIF-worthy series of odd faces, bland platitudes and lack of engagement during her single-season run.

"She's not a big talker," DeGeneres offered. "I didn't realize that," Cowell admitted with a laugh. "I kind of booked someone who couldn't talk, which is a bit of a problem when you want someone to judge." Cowell further explained that Spears was also not comfortable giving negative critiques and was even less at ease with sassy contestants who talked back to her.

"She was just uncomfortable ... I liked her ... so we decided to change it this year and I thought, 'I'll work with three girls,' because I like working with girls," Cowell said, by way of explaining why he filled Spears' and departed judge L.A. Reid's spots with ...

Rick Ross and his MMG team are dropping their Self Made Vol. 3 album in just one week, and last week MTV News caught up with them in Miami on the set of two videos, for the singles "Gallardo" and "Stack on My Belt."

"Ross is the mastermind and he put the record together," Gunplay said of the second single from the album, which features Rozay and Yo Gotti. That clip was filmed right alongside "Stack on My Belt," featuring Ross, Wale and Birdman, and was also directed by MMG's Dre Films.

"The concept behind 'Gallardo' is basically fly whips," Dre Films told MTV News. "We've got a couple [Gallardos] out here. We have beautiful women, so it's a fly record and the ladies are gonna love it. This is one of the videos that I notice has the most cameos in it. A lot of the people who are featured on Self Made Vol. 3 are in the video and I'm just glad they came out and showed love and support."

Ross explained that the song came about organically. "We was in the studio and actually there were four Gallardo Lamborghinis outside, and we pulled up a beat and we just was having fun, man," he said. "It's a real good vibe, it's for the women who really just shooting for the stars. She don't mean no harm, she just wanna be with a bawse."

"Stack on My Belt" isn't any lighter on the high-end accessories, according to Dre Films. "That's another record that we're just trying show off ...

Miley Cyrus is having a big week... and it's only Tuesday.

Along with announcing her new MTV documentary (out October 2), releasing her Bangerz track list and swinging the "Wrecking Ball" video our way, we also get to hear the pop singer on Mike Will Made It's brand-new track,

Fans have been waiting some time to hear the full track, which features the twerking pop singer rapping alongside more seasoned rhymers like Wiz Khalifa and Juicy J. An though fans are still waiting for the video for the Mike Will-produced track, Smilers are already reacting to Cyrus' turn on "23," a club jam about partying in miniskirts and Air Jordans.

"You thought Miley was cool/ratchet/hot/whatever before... wait until you here her rapping on this song," @JOPRO50 wrote, mirroring some of the sentiments Smilers felt about Cyrus' latest incarnation as a rapper. @SweetSINaMINnut added, "Miley better work...she not to bad at this rapping s--- #23."

Miley Cyrus Strips Down (In More Ways Than One) With 'Wrecking Ball' Video

A bunch of listeners were onboard with Cyrus flexing her rapping muscle. And given just how many MCs (Big Sean, Nelly, Future) are slated to make cameos on her October 8 release, Bangerz, they just might get what they are asking for. @allisonmarie94 wrote, "What's better than Miley stripping? Miley rapping #loveher #badbitch."

While not all fans could totally co-sign her attempt at rapping, they seemed to still have some positive feelings about it. "I wouldn't class her as rapping, but Miley sounds sick on this track 23, as well as ...

One listen to Paramore's new album should tell you that Hayley Williams and the guys are very interested in expanding their musical boundaries ... which is just part of the reason why Zedd recruited Williams for his new single,

Seems he's got a lot more in common with the fiery frontwoman than most folks realize.

"Although my music is electronic, it has a lot of influences from my past, which is all sorts of genres; I've been in a rock-metal band for a longtime, and I still feel like, personally, I have a lot of influence from that," Zedd told MTV News. "My classical influence, you can find spots here and there. I think we have a similar background, musically, and maybe that's why it fits so well ... I feel like a lot of other genres are in my music even though they're not in the spotlight."

And those similar sensibilities are what make "Stay the Night" — which is available digitally Tuesday — such a natural fit. Williams' soulful vocals blend seamlessly with Zedd's keening, electronic production, creating a song that's certainly ready for the clubs, but also contains nods to the rush of rock and the compositions of classical music. Though, when Zedd spoke to MTV News, he wasn't all that interested in figuring out where the track fit ... rather, he was focused on nailing his portion of the music video.

"I don't have to think about anything, I just have to play the song, but I have to play it in double speed, which ...

Daniel Radcliffe is coming back to the fantasy genre, but "

The new film from director Alexandre Aja just premiered at the Toronto International Film Festival to favorable reviews, and now, those of us not lucky enough to be in the Great White North for the fest are getting our first look at "Horns."

MTV News' Josh Horowitz spoke with Radcliffe about the role at Sundance 2013, just after he had wrapped on "Horns," and he looked back on the whole experience with a laugh. "A few weeks after we finished I woke up one morning thinking, 'What was that? What was that film I just did?'" he said. "It's so crazy. I feel like I have less concept of what it's going to be now than when I first started, which is bizarre, but it's very exciting."

"Horns" does not currently have a release date, but expect news out of TIFF soon.
