So much for doing the right thing.

Spike Lee rejected Prince Harry’s handshake in an awkward moment at Saturday’s New York Knicks vs. San Antonio Spurs game, as seen in Page Six’s exclusive video.

The filmmaker, 69, watched the Duke of Sussex, 41, hug someone in the stands at Texas’ Frost Bank Center at the NBA Finals Game 5 before saying something to the retired royal.

When Harry noticed the Oscar winner pointing at him, he doubled back and stuck his hand out.

The former military pilot then placed his hand awkwardly on Lee’s stomach as the director denied his handshake and pointed a finger at him.

The pair ultimately did shake hands while continuing to chat.

Lee pointed to himself as Harry departed — seemingly asking something along the lines of, “Who, me?” — and Harry replied with an affirmative finger point back as he walked away.

Reps for Lee and Harry did not immediately respond to Page Six’s requests for comment.

Perhaps the duo were addressing Harry’s old secret Facebook account under the alias Spike Wells, which Lee has spoken about publicly.

Lee even gave a Prince William “a message” about the social media move in 2019, requesting the Prince of Wales “ask [his brother] why he did that.”

During a subsequent “Today” show appearance, Lee told viewers, “I asked his brother to find out! When I know, you’ll know!”

Harry, who posted photos with his then-girlfriend Chelsy Davy on the account at the time, is rumored to have chosen the name Spike Wells as a combination of his longtime nickname and military alias.

He and Lee, notably, were not among the celebrities seated on celebrity row for this weekend’s star-studded NBA matchup.

Harry, who made a surprise solo appearance at the game sans wife Meghan Markle, was relegated to the eighth row.

Sydney Sweeney, Scooter Braun and more A-listers also did not watch from front and center.

Ben Stiller and Timothée Chalamet, meanwhile, did sit courtside as the New York-based team beat the Spurs for their first NBA championship in 53 years.
