Jennifer Aniston and Justin Theroux are said to have put their wedding on hold.
The couple, who were reportedly due to marry in May, were said to be unable to decide on a date and agreed to delay the nuptials "for a few months".
"Jen and Justin have been totally relaxed about the wedding planning," a source told the Daily Mail. "They're looking forward to the wedding, but they have different ideas about the actual wedding itself."

Apparently the pair are unable to agree on what kind of wedding they want. "It's not to do with them a couple," the source added. "They're madly in love. Every time you see them they've got their arms around each other.
"Jen wants something bigger with all their friends, Justin would just like something a bit more intimate.
"At this point, we're expecting the wedding to be at the end of the summer, just before the Labor Day Weekend [August 31 – September 2]."
It's not the first time the couple have hit the brakes on their wedding plans; Jen was forced to delay the nuptials due to her commitments in producing the TV movie Call Me Crazy: A Five Film.
Jennifer and Justin have been dating since 2011 and got engaged last August, after screenwriter Justin popped the question on his 41st birthday.
"Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," his spokesperson told US magazine People.
Since meeting Justin, 43-year-old Jennifer has frequently spoken of how content her partner makes her, saying she was in a "joyful and peaceful" place.
