Basketball star James Harden is well and truly in with the Kardashian-Jenner clan. He was spotted spending his weekend with his rumoured girlfriend Khloe Kardashian, and her famous reality star family. The clan celebrated Kylie Jenner’s 18th birthday and Harden was right in the thick of things with his ladylove.

According to E! Online, Kylie and most of the Kardashian-Jenner klan gathered in Malibu hotspot, Nobu, for a nice family dinner on Friday. The dinner kicked-off a weekend full of celebrations and also a lot of quality time between Khloe and the Houston Rockets star.

Showbiz website TMZ reports that apart for Kylie’s immediate family, James was also present at the Nobu dinner. He was by Khloe’s side as she celebrated with her youngest sibling. Apart from James, another notable appearance at the dinner was Caitlyn Jenner, who was spotted with her ex-wife, Kris Jenner, for the first time in public. Kylie’s other sisters, Kourtney and Kim Kardashian as well as Kendall Jenner, were also present.

On Saturday while most of the family kept out of sight, Khloe and James were inseparable. She acted as his courtside cheerleader when he played in a Drew League basketball game at the King Drew Magnet High School in Los Angeles.

James joined the Kardashian-Jenner squad again on Sunday, as they all stepped out for even more festivities. Us Weekly reports that the family, along with some close friends, had dinner at The Nice Guy in West Hollywood. The group then changed locations and enjoyed an after party at Bootsy Bellows nightclub.

TMZ shared a video of Khloe and James as they were mobbed by paparazzi outside the club. In the video, Khloe is seen being helped by a bodyguard as she got into a waiting SUV. James followed closely behind and got in the car beside her.

Despite having been seen together on several occassions, the rumored couple have not officially confirmed their relationship. They sparked speculations over the 4th of July weekend, when they were first spotted enjoying a night out in Las Vegas.
