Pamela Anderson joined Miley Cyrus onstage over the weekend to show some love to her new BFF and to save the whales.

The two pop icons have bonded over their shared passion for animal rights, so it was only fair that Pam come out to join Miley on the last show of her Dead Petz Tour.

While Miley outdid herself with her display of provocative gestures and wacky costumes, Pam looked relatively demure in a black leotard, with the slogan 'NO CAPTIVITY' written on her thigh.

The unlikely duo actually have much in common, besides animal rights. Both have been strong supporters of the LGBTQ community, and both have starred in campaigns for MAC lipstick, which funds HIV/Aids research.

An of course, both are very comfortable with nudity.

Miley appears topless on several magazine covers this month, and Pam has honor of being the last nude centerfold in Playboy magazine.

Speaking about MIley recently with Elle, Anderson had this to say:

Miley is so sweet. In this generation—and I know because I have two teenage boys—they don't really have to care about things. It's kind of a desensitized generation. I'm so impressed that she's really vegan and outspoken about animal welfare. She has written me some really beautiful letters and her mother has reached out to me. If I can be of any inspiration, I love it

It is obviously a mutual admiration society between the two women, who have both suffered public ridicule for their free-spirited, in-your-face sexuality.

Miley has been struggling in recent months with the loss of her dog Floyd. During her concert on Saturday night, Miley tried to explain to her audience what the tour meant to her. She said she wanted to be surrounded by people who understood the pain of losing a beloved animal, and who shared her belief that 'nature is always right.'

She related her conviction that the environment must be defended from 'man’s unfeeling encroachments,' according to the Los Angeles Times.

At 23, Miley is lucky to have someone like Anderson, 48, to look to as a strong role model. Miley has acted out her growing pains on the world stage, and she may want to regroup after this tour, with the help of some gown-ups who have walked that path and lived to tell.

Who better than Pamela Anderson, actress, sex symbol, mother and activist?
