German supermodel Heidi Klum has given birth to a baby boy, her husband, British pop singer Seal, said on his Web site.

Johan Riley Fyodor Taiwo Samuel was born on Wednesday, weighing 8 pounds, 11 ounces (3.9 kg), he said.

"To our children, a brother. To our parents, a grandson. To my wife and I, a son. To our family, a blessing," Seal wrote on the site (www.seal.com). "He is healthy, beautiful and looks just like his mother."

The message did not say where Klum gave birth.

Klum, 33, and Seal, 43, were married in May 2005. They have a 1-year-old son, Henry. Klum's daughter, Leni, 2, is from a previous relationship with Formula One race car manager Flavio Briatore.

Klum hosts the Bravo reality cable television show, "Project Runway," which features aspiring designers vying for a chance to get a start in the fashion world.

She gained fame in the late 1990s modeling lingerie for retailer Victoria's Secret and swimsuits, notably on the cover of Sports Illustrated magazine's popular swimsuit edition.
