Pop superstar Jennifer Lopez is reportedly prepared to dump her toyboy lover Casper Smart over claims that he sexted two transsexual models.

According to US reports, the Hit The Floor hitmaker and her 27-year-old beau have been having blazing rows after the models, Sofie Vissa and Xristina, alleged they shared intimate conversations with the former back-up dancer.

US gossip website The Dirty published a report that Smart cheated on his famous girlfriend multiple times - and was fully aware that both women were transgender.

Lopez is said to have been left embarrassed by the lurid allegations and is ready to end their two-year romance.

"The relationship is all but over," a source told RadarOnline.

"Jennifer has been embarrassed by him yet again," a friend of Lopez told RadarOnline. "He was not invited to accompany her to New York."

Until the 44-year-old star finds a new man, she has reportedly started finding ways to punish Smart.

These methods include refusing to take him to the World Cup, which starts on 12 June. Lopez recorded the tournament's official song We Are One (Ole Ola) with rapper Pitbull.

"Soccer is his [Smart's] favorite sport, so it must really suck for him," the RadarOnline source continue.

Although Lopez has not commented on the sexting rumours, this is not the first time Smart's sexuality has come into question.

In June 2012, the couple refuted reports that he was gay after one of the dancers he previously worked with claimed he dated men.

"Casper is not gay. These comments are born from envy and jealousy," the couple said in a statement. "It must be a slow news day."

Lopez started dating Smart in 2011just four months after her and then-husband Marc Anthony announced the end of their seven-year marriage.
