The acting couple have different destinations and budgets for their nuptials.
The couple recently announced their engagement, and while he bride-to-be would love to marry abroad, the groom is hoping for their nuptials to take place close to home.
A source claimed the former 'Friends' actress wants a ''destination wedding, kind of like eloping with a few friends. There will be The Feeling of a vacation, since that's their favorite thing to do.''
However actor/screenwriter Justin has other ideas.
The insider told website UsMagazine.com: ''Justin wants a New York City winter wedding.''
The tone and theme of their future nuptials is also a source of contention. Although 43-year-old Jennifer will want to ''celebrate in high style,'' the friend explained: ''Justin isn't as flashy as the men she's been with in the past, so it won't go too over-the-top.''
Though they disagree over the details, in the end, both stars are thrilled to be taking this next step together.
A source says of the 'Horrible Bosses' star, who divorced Brad Pitt in 2005: ''Jen is over the moon about her second chance at a happy marriage. Justin is giving her a solid vow to love.''
It will be the first marriage for 41-year-old Justin, who split from longtime love Heidi Bivens in early 2011 after 14 years together.
