Griffin and his rumoured girlfriend Jenner had a low-key dinner date at the Improv comedy club in Los Angeles which also saw a private performance by comedian Dave Chappelle.
The LA Clippers superstar sustained a sprained Medial Collateral Ligament (MCL) during a collision with Austin Rivers last week and that he is now expected to remain sidelined for two months.
Jenner, who recently outshined supermodel Gisele Bundchen to become the world's highest-paid model, looked elegant in a long fuzzy black-coloured sweater paired with black jeans.
Jenner was in the crowd at Madison Square Garden to watch Griffin's side 107-85 loss at the hands of New York Knicks, the TMZ reported.
Following the defeat, Griffin hit the clubs in Ney York City with Jenner and were spotted leaving Up & Down nightclub in Manhattan at the early hours of the morning, the TMZ reported.
Prior to that, the 28-year-old NBA player and Jenner were also spotted having a dinner date at Sugarfish in Beverly Hills, Calif on Sunday. (ANI)
