Speculation abounded about Heidi Klum’s pregnancy – and the supermodel’s husband Seal couldn’t keep it secret for long.

The singer’s lips weren’t sealed Thursday night when he announced to the audience at his New York concert that he and Klum are having another baby.

Klum’s representative, SaraJane Liebe, confirmed Seal’s baby announcement.

Klum has two young sons with the Grammy-winning singer, whom she married in 2005. The German-born supermodel also has a daughter from a past relationship.

The 35-year-old host of the TV series “Project Runway” chimed in on her Web site Friday, writing: “I am expecting a baby. Leni, Henry and Johan as well as Seal and I are thrilled.”
