John's lawyer calls the allegations 'patently untrue.'
Elton John is fighting back against new bombshell allegations from a former bodyguard.
Jeffrey Wenninger is suing the 69-year-old music icon for sexual harassment and battery. In a 13-page lawsuit obtained by ET, Wenninger describes, in graphic detail, three alleged incidents in March and April of 2014.

Wenninger claims that while riding in a car, John did some "unwelcome and offensive touching and groping," including putting his hands in Wenninger's pants and attempting to grab him "both over and under his clothing." Wenninger also claims that the GRAMMY winner forced "his hand down [his] shirt" and made statements like, "You gorgeous thing" and "Say hello to Uncle Elton."
Wenninger is currently a Police Lieutenant in the LAPD's Force Investigation Division, and received the Medal of Valor as an officer in 2007. Since filing the suit on Monday, Wenninger has shut down his Facebook page.

In a statement issued to ET, John's lawyer, Orin Snyder, said: "This baseless lawsuit is brought by a disgruntled former security officer seeking to extract an undeserved payment. These claims are patently untrue and contradicted by numerous previous statements made by this plaintiff. We will not give into his latest abuse of the legal system."
John is currently with his family in Venice, Italy, and is scheduled to return to his Las Vegas residency on April 16.
