The leader of the defending Eastern Conference champions caught wind of the clip and decided to publish the footage on his own Instagram account along with a message to Williams, who is pregnant.
Williams later responded to James in the comments section of his Instagram post, writing: "I first need to get this chalk clap right before I train! Hahha but indeed I'm not sure if you can keep up though lol j/k."
This wasn't the first time James shouted out Williams on social media. Last summer, he posted an Instagram photo of himself alongside the 39-time Grand Slam titlist after her seventh Wimbledon win. Williams had credited James as her inspiration after he led the Cavaliers out of a 3-1 hole to win the 2016 NBA Finals a few weeks earlier that summer.
