Anniston has left many puzzled on whether or not she is indeed expecting a baby, after it was reported that she was postponing her wedding to fiance Justin Theroux. 

Enstars reported earlier that the wedding was pushed back until the end of the summer. 

Sources close to the couple said that the two are madly in love, but don't want to rush the preparation and planning of a lavish ceremony. 

"Jen and Justin have been totally relaxed about the wedding planning. They're looking forward to the wedding, but they have different ideas about the actual wedding itself," a source said.

Other sources indicated that the main reason the wedding is postponed is because of Aniston's ex-husband Brad Pitt. 

Pitt will wed longtime girlfriend Angelina Jolie this summer and Aniston does not want her big day to coincide with Pitt's. 

"She does not want her day associated with them," a source said. 

Aniston and Theroux who both starred in the movie Wanderlust got engaged last August, after more than a year of dating. 

Over the weekend reports indicated that Aniston refused to sign a $150 million prenup because she loves Theroux and does not want to compromise their union. 

She told several friends: 'I'm choosing love, not money. And people are just going to have to deal with it," a source said.
