Jennifer Ann McCarthy-Wahlberg (née McCarthy; born November 1, 1972) is an American actress, model, television personality, and anti-vaccine activist. She began her career in 1993 as a nude model for Playboy magazine and was later named their Playmate of the Year. McCarthy went on to have a television and film acting career, beginning as a co-host on the MTV dating game show Singled Out (1995–1997) and afterwards starring in the eponymous sitcom Jenny (1997–1998). Her film roles include BASEketball (1998), Scream 3 (2000), Dirty Love (2005), John Tucker Must Die (2006), and Santa Baby (2006). In 2013, she hosted her own television talk show The Jenny McCarthy Show. From 2013 to 2014, she was a co-host of the ABC talk show The View. Since 2019, McCarthy has been a judge on the Fox musical competition The Masked Singer. McCarthy has written several books about parenting and has promoted research into environmental causes and alternative medical treatments for autism. She has promoted the idea that vaccines cause autism, and said that chelation therapy, a quack remedy, helped cure her son of autism. McCarthy's proselytization of these views has been called "dangerous", "reckless", and "uninformed". She has been described by journalists as "the nation's most prominent purveyor of anti-vaxxer ideology" and "the face of the anti-vaxx movement". She disputes the anti-vaccine label, saying she prefers the term "pro-safe-vaccine-schedule", a term that has met strong criticism.
