Seal and Heidi Klum Heidi Klum better get set for more late nights and diaper duties.

Her husband Seal has confirmed that she's expecting again.

Speaking at a concert in New York, a delighted Seal told the audience:

"The topic of debate outside our hotel is, 'Is Heidi having another baby?'"

He then revealed: "Heidi and I are having another baby." 
 
"I mean, Heidi is doing all the work," Seal continued, before breaking into his song, A Change Is Gonna Come.

Heidi herself was in the audience, and cheered Seal on as he made their special announcement.

She was joined by her three kids - Henry and Johan, her children with Seal, and Leni, her tot from a previous relationship.

The new bubba on the way means Heidi will soon be mum to four kids under the age of six; so good luck to her, we say.
