Gisele Bundchen is brushing off the fact her ex-husband Tom Brady is now dating another supermodel, Irina Shayk ... and it sounds like Gisele expected it to happen eventually.
A source close to Gisele tells TMZ ... "Why wouldn't she be happy for Tom? She divorced him. It is helpful to her freedom that he moved on."
The source says Gisele and Irina are NOT friends, but they have known each other professionally for years and have always been cordial when they cross paths.
