Jennifer Lopez revealed a few deets about her upcoming Chris Brown collaboration recently. Find out what she said inside and see what Ryan Seacrest and Randy Jackson said about rumors of Mariah Carey being replaced and watch Sean Kingston’s behind the scenes footage from the "Beat It" shoot.

We told you previously that Jennifer Lopez had hooked up with Chris Brown and producer Cory Rooney to recapture some of tha "Jenny From The Block" magic, and during an recent interview with Extra’s Mario Lopez, she offered a little more insight.  She said, 

“Yes, when we were in the studio, writing songs and just getting that ‘Jenny from the Block’ flavor back." She added, “We actually worked on a bunch of [title] ideas… and we talked about doing a duet together for his album.”

And in addition to new music, she was recently honored for her charitable efforts when Muhammad Ali presented her with a humanitarian award at Celebrity Fight Night.  She explained the origin of the Lopez Family Foundation to Mario saying,

“It’s something Lynda (her sister) and I talked about for many years… when we both got pregnant at the same time it felt like… this is the right time to start it. Let’s do it. Let’s start the Lopez Family Foundation and make it about women and children and healthcare.”

And over at "American Idol"……

"American Idol" host Ryan Seacrest talked to “Extra’s” Terri Seymour recently where he disputed rumors about Mariah Carey being replaced by Jennifer Lopez. He said, "I had not heard about that before that report. I saw Mariah that day and she was firmly planted in that seat, and I see her tonight and I think she was firmly planted in that seat, I don’t think she is going anywhere.”

Meanwhile, Mariah’s good friend and fellow "AI" judge Randy Jackson added, “It’s so weird, it sounds so ridiculous… you hear rumors about these shows all the time. This one was so ridiculous of an idea… anyway, I think that would have hurt a lot of things.”

So we guess Mariah is "safe"…..until the executives vote again!!??

And in music video previews……

Sean Kingston recently shared behind the scenes footage from his new "Beat It" video featuring Wiz Khalifa and Chris Brown. Shot at a secret location in Malibu, he told Rap-Up.com,

“I’m 23, we all grown, so you really see us in a different light. We’re in suits, hot in fashion, just very swag and everything’s real tasteful. Helicopters, luxury cars, Ferraris, classic cars…”

Colin Tilley directed the clip which will premiere on April 29. Meanwhile, Seans Back 2 Life disc drops later this year.
