He's revealed the cast of the hugely popular reality singing show had to "walk on egg shells" around the colourful former Spice Girl when she was on set of the Channel 7 show. "You just never knew what was going on," he said. Because she was such a powerhouse, you walked around on egg shells because you didn't want to upset her. Jacobz was speaking to Sami Lukis and Yumi Stynes on their mix106.5 radio show yesterday when they asked, "Is it true that the set of X-Factor is happier without Mel B." Without hesitation, Jacobz replied, "True." The X Factor host Luke Jacobz. He then went on to state that several key cast members struggled in their dealings with Mel B. I miss her because I got along very well with her, but there may be other people who might not have. It's a rare insight into the goings on behind the scenes of the glossy seven show. The larger than life personality, whose full name is Melanie Brown, was plagued by rumours and innuendo during her time on the X Factor. Some claimed she made diva demands, while others respected her straight forward approach. Brown has never shied away from admitting to being high maintenance. Of course I'm a bit of a diva. I've sold 75 million records. Who wouldn't be?," she formally told The Daily Telegraph. I'm a girly-girl. I like my lighting. I like my hair and make-up done. I like to dress up. I've flown my team over from L.A. I'm very opinionated and I'm very honest but I'm not mean. Mel B was also said to be difficult when singing at the closing ceremony of the London Olympics last year. Reports out of the UK claimed the singer had a list of requirements leading up to her performance with the Spice Girls including having a personal stylist on call. Sources also claimed she asked for family and friends to get VIP treatment at the event.
