Christian Siriano praises Klum, Seal

Project Runway winner Christian Siriano has praised Heidi Klum and Seal for their parenting abilities.

The fashion designer, who won the contest last year, told OK that the supermodel and her singer husband are fantastic parents.

"[Heidi] is the sweetest mum in the world," he said.

"She's great because she's so real, she's at home, she's in no makeup and flats and she's like, 'I don't care.'"

He added: "You go into the house, and there are kids' drawings everywhere. It's so refreshing. [Seal] is such a cool dad, I love it! They're the best."

Klum and Seal are parents to Leni, 5, Henry, 4, Johan, 2, and 3-week-old daughter Lou.

Siriano is currently working on costumes for the movie adaptation of children's book Eloise In Paris, which is scheduled for release next year.
