Lady Gaga arrived to the AMA red carpet in a very big way. Mother Monster majestically entered the red carpet on a white horse ... or at least two guys moving a faux white horse, anyway.
Lady G was dressed in a gorgeous lavender Versace (of course!) gown - she is the new face of Versace after all.
On the red carpet, she gushed about her new gig with the legendary designer and explained that Donatella was always so supportive of her career - which must explain why one of her songs on her newest album ARTPOP is called "Donatella!"
