Jamie McCarthy/Getty ImagesJessica Simpson seems to enjoy doing her planning in pairs—even if that wasn't part of the original plan.
First, the mother of two was pregnant at the same time as best friend CaCee Cobb. Now, she and sister Ashlee Simpson are both in the thick of wedding planning—and of course they're totally in it together!
"Jessica and Ashlee are very close and really supportive with each other, especially since both weddings are coming up," a source exclusively tells E! News.
"They have been doing lots of wedding stuff together. During this wedding process they both have been talking to each other about their ideas, even though they both are having very different weddings."
Jessica, who will be tying the knot with fiancé Eric Johnson over the July 4 weekend, is planning a "classic and modern" wedding, our source says, while Ashlee is shooting for more of a "Bohemian-style vibe" when she swaps vows with Evan Ross on Aug. 31.
Each plan sounds totally in keeping with the personalities of the brides-to-be, both of whom will be tying the knot for the second time.
The sisters appear to have done their research as well, going out on dates together and otherwise sizing up their future brothers-in-law.
While Jess is super-excited for her sis to marry Evan, her family also is "a big fan" of Eric.
They think "he is such a kind-hearted person and dad," the source says. "Ashlee gets along with Eric very well and is so excited for them to tie the knot...She considers him like an older brother."
As for Johnson, a former NFL player, he's taking a step back and letting his future wife put the finishing touches on their wedding.
She is "all hands-on for her wedding and her husband...is sitting back and enjoying letting Jessica make a lot of the decisions for their wedding day. He is a very laid-back guy and just loves seeing Jessica happy, especially on her big day."
And we love that about him!
Back in January, Jess talked about her upcoming nuptials and how it's important not to forget the real reason why their guests will be in attendance.
"It's easy to get wrapped up in things when you are planning your wedding," she said during a Google Plus live chat. "It's easy to get stressed out about it, and put pressure on yourself. I mean your man proposed to you, so you don't have to do anything for him, he already likes you the way you are. So, really it's just about finding the love within yourself, and accepting the love that everybody is basically there giving you."
