Khloe Kardashian and James Harden were spotted at a UFC event over the weekend. The date was reported by Daily Mail, wherein the two flaunted a lot of PDA amid rumors that their relationship is on the rocks.

The "Keeping Up with the Kardashians" star and Houston Rockets player watched UFC 192 in Houston, Texas on Saturday evening. Khloe Kardashian and James Harden were photographed holding hands throughout the event, which featured the Light Heavyweight Championship match between champ Daniel Cormier and challenger Alexander Gustafsson.

The 31-year-old reality star wore a clinging sheer outfit accessorised with her trademark large hoop earrings, while her 26-year-old NBA shooting guard beau wore an Adidas crewneck sweater. James Harden's outfit is believed to be part of his recently announced 13-year $200-million deal with the sports apparell giant.

The public outing of Khloe Kardashian and James Harden came on the heels of reports that they have been fighting over the basketball star's alleged cheating.

According to a recent report from Radar Online, allegations came out when a Philadelphia stripper named Nelly Wit Da Jelly posted an Instagram photo with James Harden on the side of the bed. The post was quickly taken down a few minutes later.

"They had a terrible fight after Khloe confronted him and demanded the truth about who he's been seeing behind her back," an insider detailed.

The source also claimed that the controversial couple has been fighting because Khloe Kardashian seems to still have feelings for her ex-husband, former NBA player Lamar Odom.

"James isn't the type of guy who'll sit back and take sh*t, and they really got into it," the source said.

"He threw it back in her face the fact that he knows she's been creeping around behind his back with her ex [Lamar]."

"James really put her in her place - she was the one calling all the shots, but she doesn't know what she wants: One week she wants his baby, the next she's having second thoughts about Lamar, then she wants to be exclusive, then she doesn't," the source explained.
