Real recognizes real: LeBron and Serena Williams share more mutual respect on social media

It's no secret that NBA superstar LeBron James of the Cleveland Cavaliers and tennis great Serena Williams have much respect for one another.

That mutual admiration was on display Friday, when Williams posted a video on her Snapchat story seemingly mimicking the famous chalk toss that James does before every game.

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.
