Hold your horses, people.

While it may be super exciting to label Khloe Kardashian and NBA player James Harden as Hollywood's latest couple, that doesn't seem to be the case—at least not yet. There's no doubt these two are enjoying each other's company, but they're in no rush to get into a serious relationship right this second.

A source tells E! News of the rumored lovers: "They're hanging out and having fun and seeing where it goes," adding, "They're not taking it too fast."

Slow and steady wins the race, right? Regardless, neither Khloé nor Harden are exactly putting up a front about hanging out together, either.

Just yesterday, these two hit up Los Angeles' Cycle House together, where they probably got their butts whooped in spin class! Khloé commemorated her tough workout by posing underneath the business' sign with Harden and two of the top instructors, Nichelle Hines and Aaron Hines.

"Post class pic with the newest members of the E! family. Welcome to family guys! Thanks for kicking my ass tonight!!! Catch @HollywoodCycle Tuesday nights at 10pm! @ahines83 @spingalnichelle @jharden13," she captioned the pic.

The Keeping Up With the Kardashians star and Harden first sparked the summer romance idea in people's minds when they were spotted at the Encore Beach Club in Wynn Las Vegas together over Fourth of July weekend.

"They were at the beach club yesterday snacking on chicken fingers and fries, salads and fruit," a source told E! News at the time. "Rick Fox and Jermaine Dupri joined them at their cabana."

The insider continued, "They were bouncing around to all their friends honestly. They sat next to each other and talked for a bit but they were more there to have fun it seemed!"

"It was all just a fun party and she looked fabulous."
