Beyonce -- Accused of Photoshopping Bikini Photo

Beyonce's thighs are so amazing, they can bend the laws of physics -- or she just got busted Photoshopping her own photos.

Beyonce posted this bikini photo to her website Tuesday, but you can clearly see one of the stairs behind her isn't level for some odd reason. Yeah, it could be the worst carpentry ever, but it's way more likely someone is terrible at concealing Photoshop on Bey's thigh gap.

It's not the first time Bey has been accused of tweaking photos -- fans accused her of increasing her gap once before ... while another showed her sitting with a visibly distorted wine glass.
