Khloe Kardashian and new beau James Harden went to dinner at E.P. and L.P. in Beverly Hills on Wednesday night, and right before exiting the restaurant James shared a very public smooch with his lady love. They haven't confirmed that they're dating, but we think their PDA says it all!

Though Khloe and James were both wearing gym clothes, their date was anything but casual. The lovebirds were inside the swanky eatery for nearly two hours, and after their romantic meal the NBA star opened the car door for Khloe. James may be young (he's 25, she just turned 31), but he clearly knows how to behave like a gentleman. The two spent the Fourth of July weekend in Las Vegas and they had absolutely no problem showing their affection for one another. The duo were photographed dancing and kissing at the Encore Beach Club pool party on Saturday, and later that night they went to dinner before stopping by Chris Brown's bash at Drai's. Have they spent a day apart since then?!

Our photographer on the scene tells X17online exclusively:
    "Khloe and James looked very comfortable around each other, like they've been dating for a while. They seemed like good friends, but when James leaned in to kiss her it was totally romantic. Khloe was so happy -- just like she used to be at the beginning of her relationship with Lamar [Odom]."

Awww! And it's not just about partying in Sin City and late nights on the town! Earlier in the day Khloe Instagrammed a shot of the two at Cycle House after their spin class -- AND she tagged him! When it goes on the gram you know it's the real deal:
