Simon Cowell's mother wants to pick his wedding venue.

The music mogul - who got engaged to make-up artist Mezhgan Hussainy last month - has reportedly agreed to Julie Cowell's desire for him to tie the knot at her church, St. Margaret's, in Rottingdean, East Sussex, South East England, where she worships.

Julie told the Daily Mirror newspaper: "I'm very excited about the wedding and I'd love him to get married at St. Margaret's. But it's up to him and Mazghan.

"I've told Simon Father Martin Morgan would be very happy if he got married there as we have a long history with the church. Simon is very committed for the first time ever which is wonderful. The wedding is very important to me."

Simon is also said to be considering having a second ceremony in Los Angeles to please his fiancee's family but friends of the 'American Idol' judge say the plans are already stressing him out.

The source said: "He doesn't want to upset Julie - they are very close. He's finding this marriage stuff stressful. He's used to making up his own mind and now has to factor in other people's feelings."

Father Morgan admitted he would be delighted to host the ceremony at his church - which is close to Brighton, where Simon grew up - but is surprised it is being considered as a possible venue.

He said: "It had not crossed my mind that the wedding would be here because Simon's such a big star."

Meanwhile, Amanda Holden - who sits alongside Simon on the judging panel of UK TV show 'Britain's Got Talent' - claims his romance with Mezhgan, 36, has made him much easier to work with.

She said: "He's a different man - more giggly, naughty and silly. Trust me, this girl is 'The One'.

"Simon's a better boss when he's in love because he just wants to go home, which means we get off earlier."
