On 2 December 2009, animal rights organization PETA released a print ad campaign for dog adoption featuring Krupa as an angel floating in a Catholic church filled with dogs, and holding a cross covering her breasts and genitalia. Krupa had previously appeared in a PETA ad campaign against the use of natural fur. In an April 2009 cover story with Aventura Business Monthly, Krupa said she was first motivated to promote PETA when she saw video of animals being skinned alive for their fur in China. She posed covered in body paint for PETA in 2015, this time for their campaign to boycott SeaWorld. She also founded an animal rescue group, Angels For Animal Rescue, with her friend Gabi Gutierrez.

Since 2010, Krupa hostes and severs as the head judge on the Polish version of Top Model.
