According to Radar Online, Justin Timberlake and Jessica Biel have been facing major trust issues!
Looks like Jessica can't trust Justin after his serial cheating throughout the 4 years they've been together.
"She wants a fidelity clause in the prenup giving her at least 500,000 USD if he cheats on her."
But Justin is not offering any fidelity clause or alimony, and it seems that Jessica won't change her mind!
An insider told Radar Online "She doesn't trust him %100 yet. Jessica figures if she gets fat during pregnancy, he'll cheat again."
