Casper Smart took a stand against recent rumors that he had cheated on Jennifer Lopez with a transgender model before news of their breakup went public last week.

British tabloid The Sun ran a story recently saying a transgender model named Xristina Marie claimed she hooked up with the 27-year-old dancer/choreographer while he was still dating Lopez. Smart is calling foul.

“There is no truth to any meeting or physical encounter,” he told Us Weekly. “I am weighing my options on the appropriate action to take against Xristina Marie and/or The Sun.”

Marie is the second transgender model to claim to have been in contact with Smart while he was Lopez's official boyfriend. It was rumored that he had also exchanged racy photos and messages with Sofie Vissa, but sources close to the dancer said the stories were completely false.

The news of Lopez, 44, and Smart calling it quits became public Friday – just days after the initial rumors. Sources told Us Magazine and TMZ that the allegations had nothing to do with the couple’s split after 2 ½ years and that it was “an amicable process that started a few months ago.”

Neither Smart nor Lopez, who recently pulled out from performing at the World Cup opening ceremony, have spoken out on their split.

E News! reported the duo were hoping to be low key about ending things. A source said he has slowly been moving out Lopez's house.

"She will definitely still keep things civil and actually still loves him," a source told E! News. "The hard part is the kids love him too. He has become a part of her family."
