Supermodel Heidi Klum says fellow Victoria's Secret angel Miranda Kerr will have no problem balancing modeling with motherhood.

"I think she'll be great!" Klum, 37, told at the Project Runway Season 8 Premiere Party at NYC's Empire Hotel. " She's very calm, a smart little cucumber that one, and she'll do just fine."

A source tells the new Us Weekly (out now) that Kerr, 27, is "thrilled" to be expecting and has been "telling all her friends, mostly other models, about it."

The news comes after the Aussie model and longtime beau Orlando Bloom, 33, secretly wed one month after announcing their engagement in June.

"She's a beautiful young lady who just got married, and they seem like a handsome couple," Klum, told Us. "They'll make a handsome baby, that's for sure!"

Klum -- who has four children and is married to husband of five years, Seal -- has one tip for Kerr: "The children show you most of the time themselves what you have to do to. You'll learn by watching them, keeping your eyes and ears open."
