Jennifer Lopez's ex-boyfriend is considering legal action against the transgender model who may have ended his romance with the pop superstar over an alleged sex tryst.

Dancer-turned-actor Casper Smart has broken his silence after a second transgender beauty went public about a reported relationship with him.

Xhristina Marie told Britain's The Sun newspaper she romanced J.Lo's ex before the couple split, but Smart insists there is "no truth" to her story, which comes less than a week after another transgender model claimed the dancer had pestered her for sexy photos after making a connection online.

In a statement issued to Access Hollywood on Sunday (08Jun14), Smart says, "There is no truth to any meeting or physical encounter. I am weighing my options on the appropriate action to take against Xhristina Marie and/or The Sun."

Lopez and Smart's split was confirmed on Friday (06Jun14), as transsexual bikini model Sofie Vissa told In Touch magazine she exchanged racy photos via text and social media with the dancer. Smart has denied her story too.

A source tells Access Hollywood, "Casper does not know this person, has never met this person, has never seen this person and most importantly never has communicated with this person via direct message or in any other manner."
