Knicks' Isaiah Hartenstein, Kourtney Kellar Expecting '7-Foot' First Child

The couple appears to expect that the baby will inherit their father's height, as Kellar jokes about a "7 foot baby loading" in her post.

Currently working through his second season in New York, Hartenstein and Kellar wed over the summer after they started dating in February 2019. Kellar boasts over 700,000 followers on Instagram alone as of post time.

Hartenstein and Kellar are expecting at perhaps the perfect time: in addition to Kellar's active modeling career, Hartenstein, working through the latter half of a two-year deal inked in the summer of 2022, appears destined for a promoted payday thanks to his stellar relief work in place of the injured Mitchell Robinson.

Since he became the Knicks' starting center on Dec. 20, Hartenstein has hauled in 11.9 rebounds a game, seventh-best in the NBA in that span. He has pulled in at least 10 boards in five consecutive games, which includes tying his career-best 20 in Saturday's win in Memphis. Hartenstein has been one of the most reliable names on the Knicks' roster over the last two seasons, notably standing as the only New Yorker to appear in all 82 games in the prior campaign.

Hartenstein will be back in the Knicks' starting five on Wednesday night when New York (23-17) faces the Houston Rockets (7:30 p.m. ET, MSG).
