Long before Brooke Burke was dominating the dance floor on Dancing with the Stars, she was married to Garth Fisher, one of the top plastic surgeons in the Beverly Hills area.
And its long been thought that Mr. Fisher made a few plastic surgery enhancements to his once bride, presumably breast implants and a nose job (rhinoplasty) procedure.
Currently there isn't any solid 'before and after' evidence regarding the nose job rumor, however its seems quite evident that Ms. Burke has in fact undergone surgery for breast implants.

As you may know, Brooke Burke is a strong proponent of living healthy, including exercise and good nutrition, which appears to be paying off nicely with her superb skin elasticity.
