Brazilian supermodel Gisele Bundchen has cancelled the Sydney leg of an Australian promotional tour amid rumours her personal life is in turmoil.

The 27-year-old was scheduled to promote her Ipanema shoe line in the city but pulled out - a day after the birth of boyfriend Tom Brady's first child with ex-girlfriend Bridget Moynahan.

A spokesperson for Ipanema says, "It's very disappointing that she's not coming but unfortunately we have to just work with her schedule, I know Tom Brady will not be accompanying her but she will have some female support as her twin Patricia and other sister, Gabriela, will be traveling with her. We are hoping to bring her back to Sydney some time next year."
