Casper Smart reportedly tried to laugh off rumours he"d had dalliances with two transsexual models.
The toy boy ex-boyfriend of Jennifer Lopez got caught up in a love scandal last week when gossip site The Dirty alleged that Casper had been "linking up" and exchanging explicit pictures with transsexual model Sofie Vissa.
A week later a second transsexual star, Xristina Marie, also claimed to have had dealings with Casper.
"Casper is telling everyone that these women are lying and that he and Jennifer are just laughing it off, but that couldn"t be further from the truth," an insider divulged to British magazine Grazia.
"It"s a huge deal - Jennifer is horrified and incredibly embarrassed. They"ve been having a tough time recently, and this seems to be the final nail in the coffin."
Earlier this week Jennifer pulled out of the World Cup opening ceremony on Thursday, before seemingly changing her mind at going ahead with the gig.
She performed her song We Are One (Ole Ola), the official song for the soccer tournament, with rapper Pit Bull and Brazilian star Claudia Leitte, but reporedtly told Casper he was not welcome to join her on the Brazilian trip.
"There are too many rumours to ignore, and Jennifer can"t stand having her name dragged through the mud. They"ve been on the rocks for a while, and now it looks like it"s officially over. She doesn"t want to give the rumours weight by splitting straight away, but she"s told him in no uncertain terms that he won"t be accompanying her to Brazil," the source added.
It"s now thought the pair have officially parted ways.
