Is Jessica Simpson getting cold feet for walking down the aisle again? The engaged Fashion Star mentor has had her mind on her forthcoming wedding to NFL player Eric Johnson since the two announced their plunge into married life 10 months ago.

Well, according to Us Weekly, it seems now the star is putting planning on hold for the time being to make sure everything is how it's meant to be.

"Everything is up in the air," a source tells Us. "She can't figure out what kind of day she wants. Some days she wants a big wedding in Hawaii, then other days she wants something closer to home."

Other sources close to the singer say that they fear the delay is due to much more than deciding location and other fine details. "She was so gung ho about planning their wedding, and now she's gone dark," they tell the magazine. "She won't commit to a date."

Nick Lachey, Simpson's ex-husband, on the other hand, had no problems ironing out his details to his summer wedding with Vanessa Minnillo. The two wed on an island in July in a very intimate ceremony of their closest friends and family.

Look for the new issue of Us Weekly with more details about Simpson's forthcoming nuptials to hit stands nationwide on Friday.
