An insider close to Heidi Klum and Seal reveals to Life & Style that the happily married (and expecting!) couple have canceled their annual plans to renew their wedding vows in Costa Careyes, Mexico, this year due to 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.
