Kim Kardashian is working out daily to get ready for her wedding, and Gisele Bundchen is working out daily ... because she's a supermodel.

Either way, both women look beautiful in their black-and-white workout outfits! We love that they're not afraid to break a sweat!

Rumors are rampant about Kim's wedding ... some reports claims she's spending $10 million on it, and others are that the whole wedding will be televised. We wouldn't be surprised considering her whole life is televised!
