Jennifer Aniston and Justin Theroux had decided to get married in May, but now they're postponing the wedding until August, since they cannot agree on the size of their nuptials.

"Jennifer 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", one insider tells. ''Jen wants something bigger with all their friends, Justin would just like something a bit more intimate."
