Kelis must be packing a major tracklist. According to Will.I.Am, the “Caught Out There” singer could be as a big as the Black Eyed Peas or at least, Fergie when her next album hits shelves. “Kelis has always been a best kept secret. The cool people know Kelis. But the majority of people just know ‘Milkshake’. I would like Kelis to show she’s an international sensation,” Will.I.Am. told Vibe recently. “I think Kelis can be that big, as big as the Peas. A lot of rappers have these labels and they don’t let their artist become bigger than them. I’ve proven that’s not me. Fergie is huge. When Fergie blew up, she was bigger than me! I believe Kelis can do the same.” As previously reported, Kelis has signed on to release her next album, tentatively titled “Fleshtones,’ through Will.I.Am and Interscope. The first single, titled “Acapella,” was released late 2009.
