Rumors ran rampant in 2011 that [lastfm link_type="artist_info"]Justin Timberlake[/lastfm] and Jessica Biel were engaged. Now rumor is they have been working with their respective lawyers to hammer out a prenup!

The latest issue of Star Magazine is saying since they got engaged over the holidays, the couple have been butting heads over everything from hammering out their prenup to becoming parents. And Justin’s serial cheating throughout their four-year romance is a big issue. “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.” But Justin is offering a cash settlement with no fidelity clause or alimony, adds the source. “But Jess won’t budge.”

Wow, what do you think about JT & Jessica’s pre-nup?

Should they really tie the knot if there are trust issues?
