'Vanderpump Rules' Stars Scheana Marie, Ariana Madix and Lala Kent Get Naked for PETA Shoot (Exclusive)

TooFab has learned that the threesome from Bravo's hit reality series shot a campaign with PETA which is set to launch in November. An insider told TooFab that the ladies stripped completely nude and were painted to look like Orca whales in symbolic protest of Sea World and the inhumane treatment of whales.

The secret shoot for the campaign that's been kept under wraps took place over the summer and will also feature Scheana, Ariana and Lala in PSA-like interview segments about the plight of orcas. Our insider also told TooFab that the three "Vanderpump" stars even became emotional while shooting the segments discussing cruelty to Orcas.

"Lala Kent in particular got very choked up while filming her interview," the individual said.

Scheana, Ariana and Lala have been avid animal rights advocates for years. This also isn't the first time we see a "Vanderpump Rules" star get naked (with a purpose).

Earlier this month, Scheana and her boyfriend, Rob Valletta, teamed up with #BareforCARE and posted the racy images to their social media pages.

Scheana, Ariana and Lala have all volunteered their time at Lisa Vanderpump owned and operated dog rescue center, Vanderpump Dogs. Ariana and Lala have been vocal about their love of animals both on and off the show, with the former even going to Lisa's home last season to ride horses.

Sea World's last captive-born baby orca, Kyara, died July 24 in the park's San Antonio location. According to the park's press release, Kyara died as a result of complications from an infection. The exact cause of her death cannot be determined until after a full post-mortem exam, but park officials believe it was likely bacterial pneumonia, which also killed Tilikum, the 36-year-old captive orca that died last February.

Last year, TooFab was first to report Lala's shocking exit from the "Vanderpump Rules" show mid-season, and online speculation has been rampant the star will return for Season 6.

An individual close to production of the Bravo series has told TooFab that Kent has been present during several shoot for the show and she's been spotted all summer on Instagram alongside Scheana and Ariana.
