The "Keeping Up with the Kardashians" star was first linked to the Philadelphia 76ers forward in late May, following Ben's brief relationship with singer Tinashe, and they enjoyed a vacation in Mexico together in August.
The romance reportedly fizzled out soon afterwards, with the beauty moving on from the fling by making out with Anwar Hadid, the brother of her best friend Bella, but now it seems Kendall and Ben are giving things another go as they were spotted getting together after the 76ers' home win against the Los Angeles Clippers on Thursday, November 01.
Kendall apparently kept her presence at the Wells Fargo Center in Philadelphia, Pennsylvania low-key, enjoying the game from a private suite, but in video footage obtained by TMZ.com, she later met up with the star athlete in the venue's parking lot, where the on/off couple climbed into a van together and headed to meet friends at Elbow Lane bowling alley.
The date took place two days before the runway beauty's 23rd birthday, which she spent in New York City, where she and pals including Bella Hadid, singer Justine Skye, and rapper Tyler, the Creator celebrated with a little karaoke and then a party at a pal's apartment.
Ben was not present for the bash as the 76ers had another home game against the Detroit Pistons on Saturday, but he and his teammates travelled to New York on Sunday to face off with the Brooklyn Nets.
Kendall and Ben have yet to comment on their rekindled romance.
