Jessica Biel and Justin Timberlake could be getting cold feet over their marriage, according to reports. Allegedly, the couple is fighting over pre-nuptial agreements and having children.

According to Star, the crux of the problem is Justin Timberlake's rumored infidelity issues. Biel wants a huge cash settlement around $500,000 if Timberlake is caught cheating while they are married in addition to other pre-nuptial agreements. Timberlake agrees a cash amount if they split, but doesn't want the cheating clause. "She thinks if he strays during the marriage, she should be royally compensated," says an insider. She wants a fidelity clause in the prenup giving her at least $500,000 if he does."

Additionally, Jessica doesn't want to have children for several years - to make sure the relationship can last and he won't leave her while she tries to shed baby weight. "If he's faithful for several years, maybe she'll agree to have a baby.  She doesn't trust him 100 percent yet. Jessica figures if she gets fat during pregnancy, he'll cheat again." 

So we have to ask - with all of these trust issues, why are they getting married in the first place?
