The show's producer and judge Donald Trump fired Mendoza on Sunday's episode after her team failed to impress him with its creation and performance of a 90-second jingle promoting Good Sam's Roadside Assistance Program, EW.com said.
Still competing this season are "American Idol" veteran Clay Aiken, comedian Arsenio Hall, comedienne Lisa Lampanelli, singer and actress Aubrey O'Day and "Real Housewives of New Jersey" star Teresa Giudice.
Already eliminated from the show were comedian Penn Jillette, "American Chopper" star Paul Teutul Sr., actor Lou Ferrigno, singers Debbie Gibson and Dee Snider, actresses Tia Carrere and Patricia Velasquez, radio host Adam Carolla, "Star Trek" actor George Takei, IndyCar team owner Michael Andretti, author Victoria Gotti and supermodel Cheryl Tiegs.
The last person standing will receive a $250,000 check to be given to a designated charity.
