Jess and Eric are said to be limiting the guest list for their upcoming nuptials to include only close pals and family members so their big day feels more intimate.

A source said: 'There will probably only be 75 to 100 guests. Jessica will definitely not invite more if she can help it. She wants to have only really close family and friends - the kind of people she speaks to a regular basis.'

The couple had originally planned to tie the knot in Hawaii at a beach ceremony over the Christmas holiday period in 2012, but postponed their nuptials after Jessica got pregnant again.

The lovebirds have now decided on having the ceremony closer to home, with Hawaii being touted as a potential honeymoon destination instead.

Another source told National Enquirer magazine: 'Jessica has always loved the Bacara Resort and Spa in Santa Barbara, and it's also a pretty convenient location for most of their guests. She just wants something classic and beautiful that takes your breath away.'

It seems the 33-year-old star -whose sister is Ashlee Simpson - isn't obsessing over the details of her big day, preferring to spend her free time immersed in her motherly duties instead.

A source commented: 'Jessica is the antithesis of a bridezilla. She won't plan out every little detail at once; she'll think about it for a bit, the do more important things - like be a mother and take care of her newborn and daughter. The wedding isn't her only priority.'
