Gisele Bundchen's got two young boys around the house, but says she doesn't have to worry about sibling rivalry.

Her baby Bejamin, who will celebrate his first birthday December 8, and Jack, Tom Brady's 3-year-old son with Bridget Moynahan, get along swimmingly!
“I’m feeling very lucky,” Gisele tells People.

“For Benjamin, his big brother is his hero,” she says. “Jack comes in and Benjamin has a big smile. He wants to follow him around. Anything he does, he’s just in awe of him like, ‘Oh my God!’”

But, of course, Jack needed some time to adjust to his baby brother. “Sometimes siblings can get in each other’s space. He was used to having all the attention and then when you have to share, you don’t like it,” she explains. “Overall they really get along and I’m very lucky.”

The supermodel admits she wants a big family, just like when she was growing up — she's one of six girls! “I want more kids for sure but I don’t know when,” she says. “Right now I have my hands full!”
