<p><br /> JLS have declared war with N-Dubz!<br /> </p><p><br /> After a few run-ins, Marvin, Aston, JB and Ortise are now thought to have had enough of the grime group with reports Fazer was 'perving' over Marvin's girlfriend at the Isle of White Festival.<br /> </p><p><br /> Marving Humes has been going out with Rochelle Wiseman from The Saturday's since the start of the year with the two now considering living together.<br /> </p><p><br /> But that did not seem to stop Fazer apparently telling the Sun newspaper at the summer festival that: "She's hot. The things I'd like to do on a Saturday, you know what I'm saying?"<br /> </p><p><br /> The rapper is also quoted in the newspaper as say that if it came to a fight, N-Dubz would win "hands down".<br /> </p><p><br /> The first time N-Dubz riled JLS was at last year's MOBO Awards where Dappy is believed to have made a dig at the boys for miming and slated them for being a "manufactured band."<br /> </p><p><br /> JLS have now apparently said of N-Dubz: "They've gone too far this time. We've got to get them back. We've put up with their nonsense for far too long."<br /> </p>
