"Diva to the dance floor again, please! Jennifer Lopez is still hard at work on her seventh studio album (anticipated release is later this year) and I got the inside scoop on just how it&amp;apos;s coming together from the diva&amp;apos;s latest hit collaborator, producer and songwriter Thaddis &amp;quot;Kuk&amp;quot; Harrell.\r\nHarrell&amp;apos;s also been in the studio with Katy Perry for her upcoming Teenage Dream (due in August), while logging quality track time with Justin Bieber on &amp;quot;Never Say Never,&amp;quot; off the Karate Kid soundtrack.\r\nSo what are the secrets Grammy-winning Harrell keeps, besides how he&amp;apos;s tweaked hits like Rihanna&amp;apos;s &amp;quot;Umbrella&amp;quot; and Beyonce&amp;apos;s &amp;quot;Single Ladies (Put A Ring On It?)&amp;quot;? He checks in with Us.\r\nUsMagazine.com: What&amp;apos;s it been like working with J. Lo? \r\nKuk Harrell: Jennifer is really, really cool and really energetic. She&amp;apos;s also one of the hardest workers I&amp;apos;ve ever seen. She doesn&amp;apos;t like to sit around, she doesn&amp;apos;t like to waste any time at all!\r\nUs: Do Marc [Anthony] or their kids, Max and Emme, ever come to the studio with her? \r\nKH: Marc was at the studio yesterday. We were actually in New York last week and the kids were there. It&amp;apos;s really cool because sometimes the kids will come by the studio and they see Jennifer in the booth and they want to go in the booth, so she&amp;apos;ll actually be recording while holding one or both of the kids. The kids are really cool because they know when she&amp;apos;s in there. They don&amp;apos;t try to sing or talk or anything when she&amp;apos;s in there, we get a couple of takes done and they get to experience the early stages behind the mic.\r\nUs: In addition to working with Jennifer, you&amp;apos;ve also logged studio hours with Justin Beiber. What&amp;apos;s he like to work with? \r\nKH: Justin is a pleasure. It&amp;apos;s great working with him because I get to be around that young energy and to see a megastar in his early stage. I&amp;apos;ve gotten to see Justin go from being just a regular little kid with his first record deal when we did &amp;quot;One Time,&amp;quot; no one had really heard of him besides his MySpace and YouTube presence. Over the past couple of years he&amp;apos;s really developed vocally. His voice has gotten deeper, so what we&amp;apos;ve had to do is everytime we record, we&amp;apos;ve had to change the key to fit his voice now. Justin is an amazing vocalist and he is also a great drummer and keyboardist.\r\nUs: Were there girls screaming outside the studio waiting for him? \r\nKH: My daughters were [laughs]. Nobody knows where we&amp;apos;re working. Three girls that screamed are my daughters.\r\nUs: I also heard you worked on the upcoming Katy Perry album. Did her fiance Russell Brand ever come to the studio? How are they interacting as a couple? \r\nKH: Russell was never around, the only time I saw Russell was when I met him at a Grammy party -- they came together. But when Katy&amp;apos;s in the studio, her personality is great, she&amp;apos;s a lot of fun. Katy&amp;apos;s amazing, she&amp;apos;s another hard worker!\r\nBy Ian Drew for UsMagazine.com.
