Priscilla Caught in Love Triangle!

ELVIS’ ex-wife, Priscilla Presley, is tangled in a bizarre tug-of-love with Larry King’s cheating wife, Shawn, and a slick-talking speech coach.

While Priscilla, 71, was going out with Richard Greene, the love cad was secretly sharing X-rated text and video messages with sex starved Shawn King, 56.

Pressed about his meetings with Priscilla, Shawn’s lover, who also claims to have been a confidant of Princess Diana, frantically denied any romance, insisting he was only trying to help her get Congress to pass a law preventing the torture of show horses.

“Priscilla Presley and I are friends,” he claims in an email.
