Nicole Kidman has dismissed rumors she's expecting another baby with singer husband Keith Urban - less than eight months after giving birth to their first child.

The star sparked baby speculation after she was photographed posing with her arms covering her stomach at red carpet events this week.

One online report claimed Kidman "tenderly stroked her stomach as she posed for snaps with co-star Hugh Jackman" during a Japanese tour to promote their epic movie Australia.

But representatives for both Kidman and Urban have denied the actress is pregnant with a brother or sister for the couple's daughter Sunday Rose, telling Access Hollywood there's "no truth" to the claims.
