A fan in Brazil was so immensely excited to be called on stage by Katy Perry, she really made full use of her opportunity.
A video on YouTube by deigismon shows a recent concert at Rock in Rio 2015.
When Katy Perry picks her to go on stage, the fan, donning a smiley bra, is so breathless she can hardly say her name.
She continues to hug Katy, pulling her head close to her breast.
She also hugs her many times and seems to cannot stop kissing the star.
At one point, she even swoops down to hug her crotch area.
Katy sure looks immensely stunned, but she was a nice sport about it.
