Ann-Margret describes her Elvis Presley connection, remembers nibbling on Pat Boone's shoulder

Ann-Margret, a '60s sex symbol who appeared opposite Elvis Presley in "Viva Las Vegas" and Bobby Rydell in "Bye Bye Birdie," continues to support our Vietnam veterans.

"It was a joy working with E.P.," the 82-year-old told Fox News Digital. "We felt music the same way. We would listen to music, we would look at each other and woo! We would be moving the same way." Stephanie Nolasco covers entertainment at Foxnews.com.

But before sparks flew with the hip-swiveling icon, Ann-Margret appeared alongside Pat Boone in 1962’s "State Fair." During one steamy scene, Ann-Margret sent hearts racing as she nibbled on the entertainer, known for his squeaky clean image.

"It was on his left shoulder!" she proudly said. "As a matter of fact, I saw him two days ago here in Los Angeles. And of course, I reminded him of that. And I did it again! He said, ‘Thank you’ – he loved it."
