Yanet Garcia: I Didn't Get Butt Implants ... It's Muy Autentico

Yanet Garcia, aka world's sexiest weatherwoman, is coming to her own defense denying her most famous asset got bigger overnight because of new implants.

Yanet tells TMZ she hasn't had any work done on her trunk as many of her fans -- she has 1.6 million on Instagram alone -- believed after she posted a clip of herself doing her weather thing in a tight black dress.

Yanet is chalking up the rumors to camera angles, which she's definitely a pro at working to her advantage.

If her butt did get bigger Yanet says it's because she exercises regularly. #GirlsWhoSquat
