Court records show Seymour and Brant withdrew divorce complaints Monday in Connecticut Superior Court.
Seymour and Brant issued a joint statement to the media saying they were reconciling and asking that their privacy be respected.
The 42-year-old Seymour became famous as a model for Victoria's Secret and "Sports Illustrated." She dated rocker Axl Rose and was in a pair of Guns N' Roses music videos prior to meeting Brant.
Seymour has been married to the 63-year-old Brant, a newsprint magnate, for 15 years. They have three children.
The reconciliation was announced as divorce proceedings were set to get started in Middletown on Monday.
