The music mogul got engaged to make-up artist Mezhgan Hussainy last Valentine`s Day (14.02.10) but rumours were rife all was not well in their relationship as they had failed to set a date to tie the knot and were spending a lot of time apart. However, Mezhgan`s mother, Mary, insists everything is good between the pair and they are busy planning their nuptials and will live together full-time when Simon moves to Los Angeles to film `The US X Factor`. Mary - who lives in Los Angeles - told the Daily Mirror newspaper: "I`m very excited about the wedding. It`s on and we▓re very happy for them. Simon is a wonderful man. "He and my daughter will be living in LA when `US X Factor` starts and we`re looking forward to seeing a lot more of them." However, she refused to reveal the actual wedding date, saying: "I really can`t comment but it`s very exciting." While Mezhgan`s mother is excited about the nuptials, Simon`s mum Julie revealed last October the couple were having a break from one another and admitted she thought they had rushed into their engagement. She said: "I think the engagement was too quick. This might give them the break they need to think it through. Marriage is a very, very big step. "It`s a break at the moment. The problem with Simon is that he works so hard." When Simon, 51, was recently questioned when he would marry 37-year-old Mezhgan, he squirmed and joked he didn`t want to upstage Prince William and Kate Middleton`s wedding in April. He said: "I don`t want to overshadow Prince William so they`ve got to go first."
