Swine flu scuttles Heidi Klum and Seal ceremony

Heidi Klum Seal

tells Life Style Weekly magazine that the two have canceled their annual plans to renew their wedding vows in Costa Careyes, Mexico, this year because of the swine flu.

"Heidi was worried about border closings and her three small children," the insider reveals. "And of course, she's pregnant."

The couple were married on May 10, 2005, and have renewed vows in the same location, and on the same date ever since.

Heidi's rep confirms the news to Life Style, saying "Heidi and Seal have decided to renew their vows at home in LA this year." This will be the couple's fourth wedding renewal.
