Demi Moore has paid a touching tribute to late actor Patrick Swayze -- using words from their 1990 movie Ghost.

The Dirty Dancing star passed away on Monday in Los Angeles after losing his two-year battle with pancreatic cancer.

Swayze went public with the illness in early 2008 and underwent regular bouts of chemotherapy as he repeatedly denied tabloid reports he was close to death after learning the cancer had spread to his liver.

Despite his determination to survive, the star's passing has shocked Hollywood and his fans alike, with touching tributes from a number of celebrities.

And his Ghost co-star Moore has now spoken out about the sad news, taking to her Twitter page to quote the pair's characters from the hit film.

She writes, "Patrick you are loved by so many and your light will forever shine in all of our lives. In the words of Sam to Molly. 'It's amazing Molly. The love inside, you take it with you.' I will miss you."

Meanwhile, Moore's husband Ashton Kutcher also took to his page on the site to express his sadness over the star's passing, writing: "RIP P Swayze," and posting a link to the actor performing a Chippendales routine with late comic Chris Farley on Saturday Night Live.
