U.S. singer and actress Jessica Simpson won't commit to a date to wed Eric Johnson, her fiance of 10 months, sources close to the couple told UsMagazine.com.
Simpson's ex-husband, recording artist and TV personality Nick Lachey married his longtime girlfriend Vanessa Minnillo in July.
"She was so gung-ho about planning their wedding, and now she's gone dark," added a second friend. "She won't commit to a date."
