The twerking queen was performing at The Wiltern in Los Angeles over the weekend when Pam joined her during a rendition of hit "We Can't Stop". Did we mention Miley was wearing a prosthetic penis the entire time...?
Famous animal rights activist Pam must be friends with Miley because of her animal-love too. She held up a sign reading "Save the whales" during the performance, while Miley donned fake breasts and that wiener.
Watch their performance, below.
