Gisele Bundchen found it hard to go back to work after the birth of her child Benjamin in December because she had spent so much time in her house.
Gisele Bundchen has "changed" since having her first child.
The 29-year-old model had baby Benjamin - her first child with husband Tom Brady - in November 2009, and admits she found it hard to get back to work.
She said: "I got to the studio and I felt like I was E.T. - whoa, what's going on? Hair and makeup?
"I'd been in my house, in a cocoon with my kids, my husband, my dogs. Usually, as I walk through the door into that atmosphere, I already feel different. There's a button that goes On and I'm On.
"This time it wasn't like that. I've been really inside with my husband and my baby, and everything is changed. But the client still deserves respect and professionalism, and I got a little bit concerned because I wasn't feeling it."
However, the Brazilian-born beauty claims she did look after her body while she was pregnant.
She said to Vogue magazine: "I did kung fu up until two weeks before Benjamin was born, and yoga three days a week.
"I think a lot of people get pregnant and decide they can turn into garbage disposals."
