The Fast and The Furious star was killed when the Porsche Carrera GT he was travelling in smashed into a tree and burst into flames in California on 30 November.
In the days following the tragedy, onlookers were stunned when a plane flew overheard carrying a 70-foot banner which read: "Our hearts go out to his friends and family. #17 Paris Hilton."
The bizarre stunt sparked a backlash against the hotel heiress on Twitter, but the star insists she had nothing to do with the message.
In a post on her own Twitter page, she writes: "I am so horrified that someone would hire a plane to fly over Paul Walker's crash site with messages from me. So disrespectful."
It's the second time this month hoaxers have left Hilton red-faced.
Following Nelson Mandela's death last week, a tweet posted on her Twitter account read: "RIP Nelson Mandela. Your 'I Have a Dream' speech was so inspiring. An amazing man."
The star later insisted the tweet was a fake and denied confusing Mandela with Martin Luther King, Jr., who famously made the speech at a civil rights rally in 1963.
