The 18-year-old model was spotted with 25-year-old NBA star Chandler Parsons on Saturday. The pair went to STK restaurant in Los Angeles with Kendall's sister, Kylie, and two friends, and "sat next to each other" at dinner.
"Kendall and Chandler were flirting throughout the meal," an onlooker told Page Six. "They laughed and chatted all night."
Parsons was drafted as a small forward by the Houston Rockets in 2011, and became a free agent after the 2013-2014 season.
He signed a three-year, $46 million contract with the Dallas Mavericks in July, and Kendall and Kylie were in the city last week to promote their new fashion line for PacSun.
Kendall was linked to One Direction singer Harry Styles in November, but the relationship reportedly ended in February. Model Paige Reifler confirmed Wednesday that she and Styles have rekindled their romance.
