Heidi Klum`s kids love her boyfriend

London: Model Heidi Klum says her boyfriend, bodyguard Martin Kirsten, is so caring that her children love his company.

The 39-year-old, who split from husband Seal earlier this year, reveals that Kirsten takes "wonderful care" of her children - Leni, 8, Henry, 7, Johan, 5, and two-year-old Lou. "They like him very much. This is also one reason why I`m so fond of him. 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," femalefirst.co.uk quoted Klum as saying. She also admits she doesn`t go public with their relationship so often because her beau prefers to keep a low profile. "Yes! I`m in love! Martin is not hiding. He`s just not the sort of guy looking for the spotlight. He prefers to stay in the background," she added. IANS
