NBA shooting guard James Harden stole a kiss from "Keeping Up with the Kardashians" star Khloe Kardashian on Wednesday night after they went to dinner at E.P. & L.P. in Beverly Hills, according to an X17 video.

The dinner followed a workout session the two enjoyed at West Hollywood's Cycle House. Kardashian posted her first Instagram photo with her rumored new boyfriend taken at the gym.

"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," Kardashian captioned the photo taken at West Hollywood's Cycle House.

In the picture, the 25-year-old NBA player and Kardashian, 31, posed with cycle instructors and siblings Aaron and Nichelle Hines, the stars of E!'s new reality TV series "Hollywood Cycle."

Kardashian and Harden sparked relationship rumors earlier this month when they were spotted dining together in Las Vegas before attending a Chris Brown concert at Drai's Nightclub.

The new romance has already caught the attention of Harden's ex, rapper Trina, who tweeted on July 5, "Sloppy seconds..." after the photos of Kardashian and the basketball pro were released.

Trina isn't alone in her sentiments as Amber Rose reportedly said earlier this week that Kardashian women enjoy her "sloppy seconds." Four months after TMZ reported Rose and Harden were seen together in New York City during the NBA All-Star weekend, Kardashian was photographed with him in Las Vegas on the July 4 holiday weekend.

Latin Post previously reported about rumors of Kardashian and the Houston Rockets star hanging out together, but according to The Daily Beast the two have gone public, hanging out poolside at the Encore Beach Club in Sin City.

Kardashian and Lamar Odom remain legally married, though the two separated late 2013 after she filed for divorce.

Harden takes the place of bad boy rapper French Montana, who Kardashian recently broke up with.
