Heidi Klum is in love, and she wants to shout it from the rooftops.

Or at least from the pages of German magazine Bunte.

The Project Runway host, 39, gushed about her bodyguard beau Martin Kirsten in a recent interview with the mag, saying, "Ich bin verliebt!" -- which translates to "I'm in love!"

Klum -- who filed for divorce from singer Seal in April, after seven years of marriage -- confirmed her romance with the South African-born Kirsten in September. Since then, the two have been spotted out and about everywhere from California to New York to Sardinia, often with the supermodel's four children, Leni, 8, Henry, 7, Johan, 5, and Lou, 3.

"This is one reason why I'm so fond of him," she told Bunte. "He's been helping me for four years now, and he takes wonderful care of the kids. He plays with them, he protects them. I trust him."

Indeed, Kirsten seems to fit quite nicely into Klum's family. Last month, the happy couple took the brood to Disneyland, where they celebrated little Lou's birthday.

"I trust him with my children's life," the German-born stunner told Katie Couric in September. "He's a great man."
