Does Khloe Kardashian have a new man? The Keeping Up With the Kardashians star was spotted dining in Las Vegas on Saturday, July 4, with none other than NBA pro James Harden.

In photos which appeared on TMZ, the reality TV star, 31, and her potential new squeeze were spotted leaving the Wynn hotel's fancy Red 8 restaurant together, and then heading to Drai's Nightclub to catch a Chris Brown performance.

But while most people will be happy to see Kardashian's love life taking a turn for the better after her failed marriage to Lamar Odom and subsequently unsuccessful relationship with French Montana, rapper Trina is not one of those people!

PHOTOS: Celebrity feuds

Taking to Twitter on Sunday, July 5, Trina had one message for the Kardashian sister: "Sloppy seconds...." followed by a throw up emoji!

"Trina thinks it is funny that Khloe was hanging out with James Harden, another of her exes," a source told Us Weekly about the feud brewing between Kardashian and Trina. "Remember French Montana was also with Trina before Khloe. Khloe and James are not officially dating though and are just friends hooking up," the source adds.

"Trina has been telling her friends Khloe can continue to have her sloppy seconds once again. Trina still hasn't spoken to Kim [Kardashian] since Khloe and French got together and you know they were good friends. Trina says Khloe may be the baddest of the Kardashians but she'll never be her," the source continued.

Oooh! We wonder how the feisty Kardashian sister will respond to that!
