I’m cool with that, so I don’t have any bad feelings.”

However, shortly thereafter, an injury forced Spears to cancel the remainder of her shows.

Shortly following that interview,Entertainment Weeklyshared its thoughts on the infamously short-lived reality show.

“Some moments with your significant other should stay private,” it noted.

In the end, the twosome largely did their wedding how they wanted.

“I just thought it would be too much if we had done it when we were supposed to.

“I want to be a young mom,” she told People in 2004.

“I can see myself as a mom.

According to the tabloid, Spears and K-Fed already had a prenup set in place.

When it came to spousal support, Britney unsurprisingly declined while requesting each party pay their own legal fees.

As we all remember, Spears fell on dark times after her divorce.

She’s very pleased [with the settlement].

The kids are with her right now.”
