When the wedding does take place, it is bound to be a very "glitzy" affair according to Simon's friend and BGT co-star David Walliams.
David shared his thoughts on the couple's big day in a new interview, admitting that it is not Simon's "style" to have a small wedding and he expects it to be a huge celebration.

"I don't think it would be in Simon's style to do a small wedding, as his 50th was a big do and I think if I was Lauren, I would want to have a big dress and glitzy, exciting party," he told The Sun.

"I'd be surprised if they just ran away to Gretna Green with two other people," David added.
Quizzed on a wedding date, the children's book author admitted that he was in the dark like everyone else. "I genuinely don't know the date of the wedding.
"I certainly haven't received an invite and I think people have read that as I'm not invited, but I don't think anyone is yet. I think only they know when and where it is going to be."

Earlier this month, Simon revealed that he and his future wife have yet to set a wedding date, telling ET Canada: "I keep reading that I am going to get married next week, next month. It's news to me! We haven't put a date on it."
Simon further shared that the ongoing speculation has even sparked concern amongst the couple's friends, who fear they have been left off the guest list.
The music mogul confirmed that people have been calling and asking why they're not invited to the wedding, to which he responds: "Because we haven't planned it yet!"
