The fashion designer even posted a cute family photo of herself, along with her sister and her new fiance shortly after she announced her engagement in January.
Still, people can't help but wonder if there is a little bit of sibling rivalry happening. Although this will be the second wedding for both Simpson sisters, it does seem like they're going to be happening kind of close to each other and there might be a tiny bit of competition between the two.
According to OK! magazine, there is more than just a little bit of bickering between the brides, with a source telling the site "it's getting nasty."
"Jessica started the feud by warning Ashlee to not rain on her wedding parade, and Ashlee told her where to go," a source tells the mag. "Jess doesn't want Ashlee using her florist and caterer. Ashlee, meanwhile, has threatened to elope in Las Vegas to spite Jessica."
GossipCop, however, investigated the claim and they were told that the story is "false."
All right, so they may not be in an all-out war over their weddings, but do you think they are even a little bit worried that one might upstage the other?
