The 25-year-old Houston Rockets shooting guard was spotted attending Fourth of July celebrations in Las Vegas this weekend with Khloe, 31.
While there have been dating rumors swirling for the past month, neither Khloe nor James were openly affectionate with each other, though she was seen sitting on his lap for a little bit, according to People.
James is known for his trademark beard, which he started to grow back in 2009 after he admitted he was too lazy to shave. He was drafted into the NBA that year by the Oklahoma City Thunder and played for that team until 2012, when he was traded to the Rockets.
Khloe was last linked to rapper French Montana, who she dated on-and-off for nearly a year.
