Jennifer Aniston allegedly doesn't want a prenuptial agreement.

Although the 44-year-old actress is worth an estimated $150 million, she is so sure about her relationship with fiance Justin Theroux that she hasn't asked the screenwriter to sign an agreement to protect her assets should they split. "Jen's absolutely adamant about not having a prenup. She told several friends, 'I'm choosing love, not money.' And people are just going to have to deal with it. It's a sweet and romantic thing to do but a number of friends are desperately worried her decision will come back to haunt her one day. No one doubts that this is a true love match and of all of the guys she's been with, everyone's confident he's a keeper. But to lay everything on the line for him seems an unnecessary risk," a source said.

However, Justin is trying to convince the Friends star to draw up a prenup because he doesn't want people to think he is just after her money. "Justin really wants a prenup because the last thing he wants is to be branded a gold-digger. He's got enough self-assurance to not feel intimidated by her fortune and he wants Jen to know that even if the marriage ends he will never take a dime from her. When he first brought it up she was blown away. But Justin has always made a point of paying his own way. Her engagement ring took a huge chunk of his fortune so she's 100 per cent sure he's not after her cash," the source added.
