No race to the altar here!

Jessica Simpson's ex-hubby Nick Lachey remarried in July, but the Fashion Star mentor is in no rush to say "I do" to fiance Eric Johnson. Although it's been over 10 months since Johnson, 32, proposed, insiders tell the new Us Weekly -- on stands Friday -- that all wedding plans have been put on hold.

"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." 

But some of the 30-year-old singer's friends fear the delay is due to more than just venue indecision. "She was so gung ho about planning their wedding, and now she's gone dark," says a pal. "She won't commit to a date."
