Jessica Simpson has reportedly postponed her wedding.

The singer-and-actress was due to wed former NFL player Eric Johnson in November but has decided to put a halt to the nuptials because she doesn't know what kind of day she wants.

A source told Us Weekly magazine: "Everything is up in the air. 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.

"She was so gung ho about planning their wedding, and now she's gone dark. She won't commit to a date."

However, her hesitance over the wedding date may be due the fact she is reportedly expecting the couple's first child and doesn't want the stress of planning the nuptials.

Jessica - who was previously married to singer Nick Lachey - has made no secret of her desire to become a mother and said she couldn't wait to have kids with Eric.

She revealed: "I definitely see myself having a family with Eric, so that's exciting to think about."
