Only weeks after giving birth to her first baby girl, Jessica Simpson has begun to plan her wedding. Thankfully, the celebrity won't have to do it all alone and has decided to go back to the planner she used for her last marriage to Nick Lachey.

Simpson and fiancée Eric Johnson had previously agreed that they would get married on November 11, 2011. The couple then decided that it would be best to wait until their daughter was born, and wait they have, although not for long. Maxwell Drew Johnson, the baby girl, was born May 1, and now a new source has declared that a wedding date has been set.

Since the couple missed out on lucky number 11, they settled on lucky number 12 and will get married on December 12, 2012, according to Life and Style magazine. The couple has been engaged since November 2010 and apparently just can't wait any longer.

"Jessica and Eric are eyeing the Hawaiian island of Kauai for the reception for around 60 family and friends," an insider told Life & Style.

To help the star plan the event while juggling a busy schedule that includes planning Maxwell's baptism and a $4 million contract with Weight Watchers, it appears that Simpson will be turning to her former wedding planner.

"Jessica is busy planning two very important events -- Maxwell's baptism and her wedding to Eric," a "pal" told Life & Style, who also confirmed that the planner would be Mandy Weiss.

Weiss also helped Simpson plan her wedding to Nick Lachey and the "Charlotte's Web"-themed baby shower she had before Maxwell was born.

Simpson has promised an original wedding as well and told E! News that she wasn't really interested in taking inspiration, not even from Kate Middleton herself.

"I got my own inspiration," Simpson told reporters in 2011.
