"He's our teacher and, most importantly, he's a person that I admire and that I trust. It's so good to have that kind of energy, to have my kids around that type of energy."

She had also denied "absurd" romance rumors involving billionaire developer Jeffrey Soffer. "I have zero relationship with him in any way," Gisele told the magazine. "He's Tom's friend, not my friend."
