Khloe Kardashian and Tristan Thompson are going strong and according to a new report, the Keeping Up With the Kardashians star was recently officially welcomed to the Cleveland Cavaliers.

After months of dating Thompson, Kardashian was reportedly welcomed to the wives and girlfriends' group of the team by Lebron James' wife, Savannah James.

“It’s becoming very apparent to everyone in Cleveland, including LeBron James‘ wife Savannah [James], that Khloe Kardashian is here to stay,” an insider told Hollywood Life on Sunday. “Savannah is such a class act and sent Khloe the kindest Christmas card ever, welcoming her into the Cavs family!"

"LeBron rants and raves about how good and competitive Tristan is and how much happier he is on and off the court and that’s all because of Khloe," the source continued. "It was extremely important for Savannah to make Khloe part of the Cavs’ family because by the looks of things, sooner or later she’s going to become part of Tristan’s family. Like LeBron, Savannah’s sort of the captain of the other players wives and girlfriends and getting her approval is a big deal!”

Kardashian began dating Thompson in late summer after filing for divorce from husband Lamar Odom for the second time this past May.
