BRIT Award winners JLS are busy working on their sophomore effort, a project they will be at work at for much of the summer. “We’re with Labrinth this week and will be back and forth to LA to work o the album over the summer,” Marvin Humes of JLS told Daily star this week. “Weâre doing tracks with Stargate and Toby Gad, who has worked with Beyoncé. Emails are going back and forth with Jason Derulo about setting up time with him too.” As previously reported, JLS is hoping to make a stateside (U.S.) debut later this year, with the help of some of R&B and Hip Hop’s top acts including Rihanna and Jay Z. The group’s debut album has sold over one million copies to date.
