's engagement ring
might be big
, but the X Factor
judge tells PEOPLE that her wedding will be just the opposite.
The former Destiny's Child singer, 32, who got engaged
to her boyfriend and manager, Tim Witherspoon, over Skype, says that while she hasn't set a date yet, she knows just what kind of ceremony she wants to have.
"I think we just really want it to be us and our pastor. That's it," she says. "I mean, we are the only two that's going to be in the marriage."
And she's not planning to spend tens of thousands on a big reception with a sit-down dinner for hundreds of friends or family, either.
So her pal Beyoncé
and fellow X Factor
judges Demi Lovato
and Simon Cowell
shouldn't be keeping an eye out for that Save-the-Date card.
"You have to pay for food for everyone and I'm not down with that," she says with a laugh. "Everyone is there just to be nosy and see who I'm wearing, you know. I'm okay."
